Recovery currently has a random mix of messages printed to stdout and
messages printed to stderr, which can make logs hard to read. Move
everything to stdout.

Change the applypatch function to take meaningful arguments instead of
argc and argv. Move all the parsing of arguments into main.c (for the
standalone binary) and into install.c (for the updater function).
applypatch() takes patches as Value objects, so we can pass in blobs
extracted from the package without ever writing them to temp files.
The patching code is changed to read the patch from memory instead of
a file.
A bunch of compiler warnings (mostly about signed vs unsigned types)
are fixed.
Support for the IMGDIFF1 format is dropped. (We've been generating
IMGDIFF2 packages for some time now.)

Make sure file is valid before we try to read it. Also free all the
strings we allocate in various functions so we don't leak memory.

Add functions less_than_int() and greater_than_int() that interpret
their args as ints and do the comparison. ("<" and ">" operators, if
implemented, should do string comparison.) This lets us do the build
time check currently done by the check_prereq binary.

A few more changes to edify:
- fix write_raw_image(); my last change neglected to close the write
context, so the written image was corrupt.
- each expression tracks the span of the source code from which it
was compiled, so that assert()'s error message can include the
source of the expression that failed.
- the 'cookie' argument to each Function is replaced with a State
object, which contains the cookie, the source script (for use with
the above spans), and the current error message (replacing the
global variables that were used for this purpose).
- in the recovery image, a new command "ui_print" can be sent back
through the command pipe to cause text to appear on the screen.
Add a new ui_print() function to print things from scripts.
Rename existing "print" function to "stdout".

Adds more edify functions for OTAs:
is_mounted getprop apply_patch apply_patch_check apply_patch_space
write_raw_image write_firmware_image package_extract_file
This allows us to install radios, hboots, boot images, and install
incremental OTA packages.
Fixes a couple of dumb bugs in edify itself:
- we were doubling the size of the function table each time it was
*not* full, rather than each time it was full
- "no such function" errors weren't visible to the parser, so they
didn't prevent execution of the script.

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.
