Subject: TWRP-ify AOSP code

Pull in most TWRP sources
Stub out partition management code
Make it compile -- probably will not boot
Kind of a mess but have to start somewhere

+ *
+ *   <mount_flags> is a comma separated list of flags that can be passed to the

+ *                 ro, rw, remount, defaults.
+ *
+ *   <fs_options> is a comma separated list of options accepted by the filesystem being
+ *                mounted.  It is passed directly to mount without being parsed
+ *
+ *   <fs_mgr_options> is a comma separated list of flags that control the operation of
+ *                     the fs_mgr program.  The list includes "wait", which will wait till
+ *                     the <source> file exists, and "check", which requests that the fs_mgr 
+ *                     run an fscheck program on the <source> before mounting the filesystem.
+ *                     If check is specifed on a read-only filesystem, it is ignored.
+ *                     Also, "encryptable" means that filesystem can be encrypted.
+ *                     The "encryptable" flag _MUST_ be followed by a : and a string which
+ *                     is the location of the encryption keys.  I can either be a path
+ *                     to a file or partition which contains the keys, or the word "footer"
+ *                     which means the keys are in the last 16 Kbytes of the partition
+ *                     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.
