39119ad8ec edify: Some clean-ups to libedify.
- Remove dead declarations in expr.h: SetError(), GetError(),
  ClearError().
- Remove the declaration of Build() out of expr.h.
- Use std::unordered_map to implement RegisterFunction() and
  FindFunction(); kill FinishRegistration().
- Add a testcase for calling unknown functions.

Test: mmma bootable/recovery; recovery_component_test passes.

59dcb9cbea edify: Move State.script and State.errmsg to std::string.
This way we kill a few strdup() and free() calls.

Test: 1. recovery_component_test still passes;
2. Applying an update with the new updater works;
3. The error code in a script with abort("E310: xyz") is recorded into
last_install correctly.

162558382b Allow recovery to return error codes
Write error code, cause code, and retry count into last_install. So we
can have more information about the reason of a failed OTA.

Example of new last_install:
@/cache/recovery/block.map     package name
0                              install result
retry: 1                       retry count (new)
error: 30                      error code (new)
cause: 12                      error cause (new)

Details in:
go/android-ota-errorcode

e5d5ac76cc minor recovery changes
- add the --just_exit option to make recovery exit normally without doing anything
- make it possible to build updater extensions in C++
- add the clear_display command so that the updater binary can request
  recovery switch to the NONE background UI

These are all used to support the notion of using OTA as a factory
reflash mechanism.

512536a54a relocate applypatch; add type system and new functions to edify
- Move applypatch to this package (from build).

- Add a rudimentary type system to edify:  instead of just returning a
  char*, functions now return a Value*, which is a struct that can
  carry different types of value (currently just STRING and BLOB).
  Convert all functions to this new scheme.

- Change the one-argument form of package_extract_file to return a
  Value of the new BLOB type.

- Add read_file() to load a local file and return a blob, and
  sha1_check() to test a blob (or string) against a set of possible
  sha1s.  read_file() uses the file-loading code from applypatch so it
  can read MTD partitions as well.

This is the start of better integration between applypatch and the
rest of edify.

47cace9836 add file_getprop() to updater
Add a function to read a property from a ".prop"-formatted file
(key=value pairs, one per line, ignore # comment lines and blank
lines).  Move ErrorAbort to the core of edify; it's not specific to
updater now that errors aren't stored in the app cookie.

d9c9d10d9d fixes to edify and updater script
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".

9931f7f3c1 edify extensions for OTA package installation, part 1
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).
