Mark Salyzyn 256d339413 fs_config_generate: add -P <partitionlist> option
Add a -P option to fs_config_generate that allows us to filter on
a comma separated partition whitelist or minus prefixed -blacklist.
A partition is defined as accessible as <partition>/ or
system/<partition>/.

No change for legacy, where no -P flag is specified.

For system.img, but not vendor, oem or odm file references:
fs_config_generate -P -vendor,-oem,-odm

For vendor.img file references:
fs_config_generate -P vendor

For oem.img file references:
fs_config_generate -P oem

For odm.img file references:
fs_config_generate -P odm

Add and fortify tests for each of these cases.

Elliott Hughes 2d7c86dfea Revert "Revert "Merge changes from topic 'fsconfig-2'""
This reverts commit fad4b4b715.

Incorporating the following fixes:

1.

fsconfig: fix fs_config_* build for discovered headers

When android_file system_config.h is picked up from the device
directory, neither TARGET_FS_CONFIG_GEN or TARGET_ANDROID_FILESYSTEM_CONFIG_H
are specified. Thus, the build is not generating the required fs_config_files
and fs_config_dirs.

Test: Ensure that make fs_config_files works, and produces the same output as before
      Build the system image and mount it as a loop back and dump the file system
      capabilities with getcap. Verify that output to the supplied
      android_file system_config.h

From the loopback of the system.img mount, from CWD system/bin:
$ getcap *
cnss-daemon = cap_net_bind_service+ep
hostapd = cap_net_admin,cap_net_raw+ep
imsdatadaemon = cap_net_bind_service+ep
ims_rtp_daemon = cap_net_bind_service+ep
logd = cap_setgid,cap_audit_control,cap_syslog+ep
mm-qcamera-daemon = cap_sys_nice+ep
pm-service = cap_net_bind_service+ep
run-as = cap_setgid,cap_setuid+ep
surfaceflinger = cap_sys_nice+ep
webview_zygote32 = cap_setgid,cap_setuid,cap_setpcap+ep
webview_zygote64 = cap_setgid,cap_setuid,cap_setpcap+ep

Compared to the android_filesystem_config.h:
    { 00700, AID_CAMERA,    AID_SHELL,     (1ULL << CAP_SYS_NICE), "system/bin/mm-qcamera-daemon" },
    { 00755, AID_SYSTEM,    AID_SYSTEM,    (1ULL << CAP_NET_BIND_SERVICE), "system/bin/pm-service" },
    { 00755, AID_SYSTEM,    AID_SYSTEM,    (1ULL << CAP_NET_BIND_SERVICE), "system/bin/imsdatadaemon" },
    { 00755, AID_SYSTEM,    AID_RADIO,     (1ULL << CAP_NET_BIND_SERVICE), "system/bin/ims_rtp_daemon" },
    { 00755, AID_SYSTEM,    AID_SYSTEM,    (1ULL << CAP_NET_BIND_SERVICE), "system/bin/cnss-daemon"},

2.

fsconfig: fix error message for duplicate AID

Fixes:
    raise ValueError('Duplicate aid value "%u" for %s' % value,
TypeError: %u format: a number is required, not str

and

    raise ValueError('Duplicate aid value "%s" for %s' % value,
TypeError: not enough arguments for format string

3.

fsconfig: add test for duplicate ranges

Add a test for duplicate range detection.

4.

fsconfig: skip AID_APP, AID_USER and all ranges

Do not output AID_APP, AID_USER and ranges. A range
is defined as ending with AID_ and ending in _START or
_END.

5.

fsconfig: test for skip AID_APP, AID_USER and all ranges

Test against AIDs that caused the bionic tests to fail.

William Roberts 92ec0ab5e8 fs_config: add unit tests
Add some initial unit tests.

The unit tests themselves are inlined into the tool and
can be executed by running the "test" commandlet.

Example:
$ python -m unittest test_fs_config_generator.Tests
.............
----------------------------------------------------------------------
Ran 13 tests in 0.004s

OK

Test: run the test commandlet and observe for failures.

William Roberts 7fe8b6d817 fs_config: drop fs_config_files/dirs PRODUCT_PACKAGES requirement
When configuring fs_config_files or fs_config_dirs for file_system
capabilities, drop the requirement that OEMs must add the target
to PRODUCT_PACKAGES. This limits the configuration requirement
to only needing to set the new and preferred TARGET_FS_CONFIG_GEN
or the older TARGET_ANDROID_FILESYSTEM_CONFIG_H method.

Test: That only setting TARGET_FS_CONFIG_GEN results in passwd and
group in the build image.

William Roberts 5f059a7691 fs_config: limit characters for AID_<name> sections
When generating files restrict the characters allowed in
AID_<name> to upercase, numbers, and underscores.

This detects errors ahead of time for generated C files as
well as handles seperation characters for passwd/group files.

This also lends itself to automatic detection of collisions
on friendly names, since freindly names are the lowercase
version of <name>.

Test: That invalid aid values result in a build failure.
Test: That the output files are consistent with ones before
this change (hash and diff checks)

William Roberts cfc51f5347 fs_config: generate oem AID header 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.

William Roberts db616f0091 fs_config: correct README
Testing on earlier versions of Python indicated an error in the
README. Python's ConfigParser prior to version 3.2 allows for
sections within the same file to override later sections.
Correct the README.

Test: Checked diff and hash of output file from before and after.
