Adds the following edify functions:
mount unmount format show_progress delete delete_recursive
package_extract symlink set_perm set_perm_recursive
This set is enough to extract and install the system part of a (full)
OTA package.
Adds the updater binary that extracts an edify script from the OTA
package and then executes it. Minor changes to the edify core (adds a
sleep() builtin for debugging, adds "." to the set of characters that
can appear in an unquoted string).

Edify is a simple scripting language for OTA installation, to be used
when we move to OTAs being installed via binaries shipped with the
package.

Allow installation of OTA packages which do not contain an
update-script, but instead contain an update-binary.

Amend (aka the recovery command language) had a half-implemented
scheme of limiting which commands OTA packages were allowed to
execute. It's not clear what this was ever supposed to be good for.
Remove it.

Change the recovery UI so that when there is a hboot or radio update
pending (which the user most do a home+back reboot to actually
install), the UI tells them so, instead of saying "Install from sdcard
complete."

Remove the memory alignment that mysteriously made OTA installs work,
in anticipation of a kernel that fixes the actual problem. Handle
EINTR properly.

In donut, OTA installation often encounters the write() system call
doing short writes -- which is legal but unexpected -- or failing with
ENOSPC when plenty of space is available. Passing aligned memory
buffers to write() appears to prevent (or at least reduce the
frequency) of these problems. b/1833052 has been filed to look at the
underlying problem, but this change aligns buffers we use with write()
so we can OTA for now (or see if this problem still occurs).

minzip fails if write() doesn't write all the data in one call.
Apparently this was good enough before, but it causes OTAs to fail all
the time now (maybe due to the recently-submitted kernel)? Change
code to attempt continuing after short writes.
