Generate an OEM AID_<name> header file seperate from fs_config
header file and provide details on how to export this interface
into native code.
Test: That ls, ps, chown and services function for built in
services as before.

Implement an android_id generator that takes the data
acquired from parsing private/android_filesystem_config.h
and generates the android_id friendly name to uid mapping
for consumption in Bionic.
Test: That ls, ps, mkdir, chown, chgrp and services for built
in names work.

Rather than hardcode the OEM ranges, parse and extract
AID values from android_filesystem_config.h.
An AID is defined to the tool as:
* #define AID_<name>
An OEM Range is defined to the the tool as:
* AID_OEM_RESERVED_START
* AID_OEM_RESERVED_END
or
* AID_OEM_RESERVED_N_START
* AID_OEM_RESERVED_N_END
Where N is a number.
While parsing, perform sanity checks such as:
1. AIDs defined in the header cannot be within OEM range
2. OEM Ranges must be valid:
* Cannot overlap one another.
* Range START must be less than range END
3. Like the C preproccessor, multiple matching AID_<name> throws
en error.
The parser introduced here, prepares the tool to output android_ids
consumable for bionic.
Note that some AID_* friendly names were not consistent, thus a small
fixup map had to be placed inside the tool.
Test: tested parsing and dumping the data from android_filesystem_config.h
file.

This internally structures fs_config_generator.py to be able
to plug in generators to produce different outputs. This
prepares this tool for group and pwd file outputs.
Test: Checked diff and hash of before and after files.

Test: Tested build for basic boot and functionality.

Introduce TARGET_FS_CONFIG_GEN, an option for generating
android_filesystem_config.h files from multiple intermediate
file formats. See the README for more details.
