A filesystem manager library to mount filesystems for init. Instead of specifying in init what to mount, and having various hacks in init itself to deal with encryption, use a filesystem manager library to do the work, that can also be invoked by vold when mounting an encrypted volume. Keep all the magic filesystem info an a device specific fstab file.

fs_mgr: pass sehandle to ext4 format routine When fs_mgr_do_format() is executed, fs_mgr creates a new blank data file system. However, that filesystem is not labeled and causes some unlabeled denials on early boot. Example Denial: avc: denied { search } for pid=2535 comm="logd" name="/" dev="mmcblk0p9" ino=2 scontext=u:r:logd:s0 tcontext=u:object_r:unlabeled:s0 tclass=dir permissive=1 To correct this, pass sehandle to the internal ext4 routine. This way the ext4 filesystem will be labeled at creation and the root inode will have a label.

fs_mgr: support using libavb to enable dm-verity external/avb/libavb provides the new Android Verified Boot (AVB) flow. It has different verity metadata format than previous formats in fs_mgr_verity.cpp fs_mgr should support using libavb to read the metadata (a.k.a. HASHTREE descriptor in AVB) to enable dm-verity in kernel. Two important files in this commit: - fs_mgr_avb_ops.c: an implementation of struct AvbOps* for libavb to do platform dependent I/O operations, e.g., read_from_partition. - fs_mgr_avb.cpp: it reads the metadata (a.k.a. vbmeta images in AVB) from all partitions, verifies its integrity against the values of androidboot.vbmeta.{hash_alg, size, digest} passed from bootloader in kernel command line. Then enable dm-verity for partitions having the corresponding HASHTREE descriptor and with an 'avb' fstab flag.

Remove "_host" and "_static" suffix from libsparse definition. This now combines all the "libsparse" libraries into the same soong target. A minor side-effect of this change is that the libsparse static library depends on the libz shared library instead of the libz static library. This minor change has no effect since targets using the static libsparse library need to explicitly include either the static libz or the shared one.
