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.
