Introduce a generator that outputs passwd files per man(5) passwd.
Succinctly, the output is a colon delimited string containing the following
fields:
* login name
* encrypted password (optional)
* uid (int)
* gid (int)
* User name or comment field
* home directory
* interpreter (optional)
Multiple colon delimited lines may exist, but will not be separated
across lines.
When run, produces:
foo::2900:2900::/:/system/bin/sh
foo_bar::2901:2901::/:/system/bin/sh
custom_oem1::2902:2902::/:/system/bin/sh
Note that this generator allows for 0 or more config.fs files. This allows for:
* Unconditional inclusion of /system/etc/passwd in the generated image
* A blank passwd file if no config.fs files are specified.
This ensures that when OEMs add config.fs files, there is no additional steps
for proper functionality (simpler for OEMs).
The one draw back is the additional inode consumption on system for a possible
blank file.
Test: That it produces a valid passwd file.

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.

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.

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.

Multiple files added to TARGET_ANDROID_FILESYSTEM_CONFIG_H will build,
however the tooling will only respect the first header found. The
sanity check in the makefile will only check the first path found for
proper naming convention. One can end up with a successful build that
does not respect all files in the TARGET_ANDROID_FILESYSTEM_CONFIG_H.
Check that one and only one item is set to
TARGET_ANDROID_FILESYSTEM_CONFIG_H variable.
Output:
*** Multiple fs_config files specified, see "device/lge/bullhead/two/android_filesystem_config.h device/lge/bullhead/one/android_filesystem_config.h"..

fs_config_generate_$(TARGET_DEVICE) is built based off the content
of $(TARGET_ANDROID_FILESYSTEM_CONFIG_H). We also add the rules
fs_config_dirs and fs_config_file to utilize this command
for target contents:
fs_config_generate_$(TARGET_DEVICE) -D -o system/etc/fs_config_dir
fs_config_generate_$(TARGET_DEVICE) -F -o system/etc/fs_config_file
In order to use this feature, one must have the fs_config_dirs and
fs_config_files in the $(PRODUCT_PACKAGES) list defined in the
device make files in $(TARGET_DEVICE_DIR). And either an
android_filesystem_config.h file in that directory, or define a
path in TARGET_ANDROID_FILESYSTEM_CONFIG_H to point to one.

- move to libcutils.so and libselinux.so as shared now that
they are in DISTTOOL.
- liblog dependency is part of libcutils, and need not be
called out explicitly now. liblog is in DISTTOOL.
- libcutils fs_config has the right to add Android logging

Update the OTA generation script to understand SELinux file
labels and file capabilities.
Make fs_config aware of SELinux labels and file capabilities, and
optionally output those elements whenever we output the
UID / GID / file perms. The information is emitted as a key=value pair
to allow for future extensibility.
Pass the SELinux file label and capabilities to the newly created
set_metadata() and set_metadata_recursive() calls. When the OTA
script fixes up filesystem permissions, it will also fix up the SELinux
labels and file capabilities.
If no SELinux label and capabilities are available for the file, use
the old set_perm and set_perm_recursive calls.

Make fs_config aware of SELinux contexts, and output the context
whenever we output the UID / GID / file perms.
Pass the selinux context to the set_perm2() and set_perm2_recursive()
calls. When the OTA script fixes up filesystem permissions, it will
also fix up the SELinux context on the files.
