Add the command line option to select the work directory and save the
updated image files. Because some people might have interested in
getting updated images from an ota file.
Also, fix a minor issue that the destination of package_extract_file
needs to be updated if it's a block device. Otherwise, an unintended
file may be extracted in the callers' directory.
Test: run simulation, run unit tests

Add a command line parser. Also add the support to parse the oem
property file and skip certain functions.

Test: run simulator for wear builds

The simulator skips executing the operations for dynamic partitions, and
will use the logical images under target_files/IMAGES directly. (Similar
to the targets without DAP enabled)

Test: run update on cuttlefish, run simulator
Change-Id: Id318d97ece4560df9f20dc5cabeb8b2e261bdf9c
The TargetFile class parses a target-file and provides functions to read
its contents. And the BuildInfo tries to simulate the device with files
on host. Some work it does includes parsing the build properties,
and extracting the image files for partitions specified in the fstab.

Test: unit tests pass, run simulator with cuttlefish, wear devices and from extracted TF.

Implement the simulator runtime and build the updater simulator as a host
executable. The code to parse the target-files and mocks the block devices
will be submitted in the follow-up.
