Reduce libs needed for decrypt and clean up old decypt files

Trim cryptfs.c to remove functions that TWRP does not use for
decrypt and remove the need for libfs_mgr from cryptfs.c by
passing some items to cryptfs.c from the partition manager.

Add support for new fstab flags:
encryptable and forceencrypt=/path/to/cryptokey
For example:
flags=forceencrypt=/dev/block/platform/sdhci-tegra.3/by-name/MD1
Note that "footer" is the default, so you do not need to set this
flag on devices that use the footer for the crypto key.
Also add mounttodecrypt if you need to mount a partition during
the decrypt cycle for firmware of proprietary libs.

Clean up decrypt and only support one version

Android 5.0 lollipop decrypt should be backwards compatible with
older versions so we will only support one version, 1.3 that came
with 5.0 lollipop.

Remove support for Samsung TouchWiz decrypt. It does not work with
the latest versions of Samsung encryption anyway and it has not
been updated to work with any AOSP decryption higher than 1.1

- *                     containing the filesystem.
- *
- * When the fs_mgr is requested to mount all filesystems, it will first mount all the
- * filesystems that do _NOT_ specify check (including filesystems that are read-only and
- * specify check, because check is ignored in that case) and then it will check and mount
- * filesystem marked with check.

-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain

-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,

-
-   3. Grant of Patent License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,

-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
-
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-

- * Run a command while logging its stdout and stderr
- *
- * WARNING: while this function is running it will clear all SIGCHLD handlers
- * if you rely on SIGCHLD in the caller there is a chance zombies will be
- * created if you're not calling waitpid after calling this. This function will
- * log a warning when it clears SIGCHLD for processes other than the child it
- * created.
- *
- * Arguments:
- *   argc:   the number of elements in argv
- *   argv:   an array of strings containing the command to be executed and its
- *           arguments as separate strings. argv does not need to be
- *           NULL-terminated
- *   status: the equivalent child status as populated by wait(status). This
- *           value is only valid when logwrap successfully completes. If NULL
- *           the return value of the child will be the function's return value.
- *   ignore_int_quit: set to true if you want to completely ignore SIGINT and
- *           SIGQUIT while logwrap is running. This may force the end-user to
- *           send a signal twice to signal the caller (once for the child, and
- *           once for the caller)
- *   log_target: Specify where to log the output of the child, either LOG_NONE,
- *           LOG_ALOG (for the Android system log), LOG_KLOG (for the kernel
- *           log), or LOG_FILE (and you need to specify a pathname in the
- *           file_path argument, otherwise pass NULL).  These are bit fields,
- *           and can be OR'ed together to log to multiple places.
- *   abbreviated: If true, capture up to the first 100 lines and last 4K of
- *           output from the child.  The abbreviated output is not dumped to
- *           the specified log until the child has exited.
- *   file_path: if log_target has the LOG_FILE bit set, then this parameter
- *           must be set to the pathname of the file to log to.
- *
- * Return value:
- *   0 when logwrap successfully run the child process and captured its status
- *   -1 when an internal error occurred
- *   -ECHILD if status is NULL and the child didn't exit properly
- *   the return value of the child if it exited properly and status is NULL
