ioutil.ReadDir returns []os.FileInfo, which contains information on
each entry in the directory that is only available by calling
os.Lstat on the entry. Finder only the name and type (regular,
directory or symlink) of the files, which on Linux kernels >= 2.6.4
is available in the return values of syscall.Getdents.
Replace ioutil.ReadDir with a call that uses syscall.Getdents
directly and collects the type information from the result.
Testing with:
rm -f /tmp/db && strace -fc finder -names Android.mk,Android.bp,Blueprints,CleanSpec.mk,TEST_MAPPING -exclude-dirs .git,.repo -prune-files .out-dir,.find-ignore -db /tmp/db .
Before:
7.01 52.688304 63 833398 1 lstat
1.90 14.246644 68 210523 getdents64
1.25 9.370471 90 104286 1 openat
After:
3.48 12.201385 117 104286 1 openat
3.06 10.729138 51 210523 getdents64
1.70 5.951892 57 104283 1 lstat
Pros:
Avoids 729115 calls to lstat.
Cons:
Requires copying ~200 lines of finicky buffer parsing code.
Puts all getdents calls (and possibly fallback lstat calls) onto
a non-blocking file descriptor, which will cause it to block a
thread and not just a goroutine.
Only works on Linux and Darwin.

directory or symlink) of the files, which on Linux kernels >= 2.6.4

In preparation for using syscall.Getdents, switch filesystem.ReadDir
to return an interface that only contains the information that will
be available from syscall.Getdents.

Combining static jars from dependencies may bring in module-info.class
files, which don't make sense once multiple modules have been combined,
and sometimes confuse downstream tools like desugar. Strip them out
like make does when combining jars.

Added three properties (soc_specific, device_specific, and
product_specific) that shows what a module is specific to.
`soc_specific: true` means that the module is specific to an SoC
(System-On-a-Chip) and thus need to be installed to vendor partition.
This has the same meaning as the old `vendor: true` setting.
`device_specific: true` means that the module is specific to the entire
hardware configuration of a device includeing the SoC and off-chip
peripherals. These modules are installed to odm partition (or /vendor/odm
when odm partition does not exist).
`product_specific: true` means that the module is specific to the
software configuration of a product such as country, network operator,
etc. These modules are installed to oem partition (or /system/oem when
oem partition does not exist). These modules are assumed to be agnostic
to hardware, so this property can't be true when either soc_specific or
device_specific is set to true.

Previously, these variables were exported only by makevars.go,
but those values are not available to config.mk. This CL adds
the variable to ui/build/config.go, which also makes it
available to config.mk.

add -e option to support it.
