Currently, the command line argments is being processed in multiple
places. In the main soong_ui arguments, there are several if statements
that checks if a specific argument was specified in order to execute
the requested operation. This does not scale well when adding or
removing a command in the near future. In order to support the build
commands (m, mma, etc...) from the envsetup.sh in soong_ui, a refactor
was required in order to add a command rather quickly and to have the
flexibiity to unit test the command. The soong_ui arguments format is
as follows:
soong_ui <command> [<arg 1> <arg 2> ... <arg n>]
The <command> is a specific operation to be executed. The arguments
after the command are processed by the command itself.
Below is the list of changes made in this commit:
* Created a new command infrastructure that allows adding
or deprecating a command easily.
* Fixed a bug when running ./soong_ui.bash directly would cause
a panic due to index being out of range for args list.
Bug: b/130049705
Test: Below is the list of testing done on this commit:
* Ran lunch and verified that the output is the same as the the output
without the modifications. lunch indirectly runs soong_ui passing

TARGET_PRODUCT) and --dumpvars-mode (to build the build cache).
* Ran ./soong_ui.bash directly (with unsupported flags and no flags)
and the proper message appeared that soong native UI is not yet
available.
* Ran m, mm, mmm, mma, mmma commands.
* Ran the make installclean command:

The zip file format does support scripts/programs prefixed to the
archive, though many of the offsets are supposed to start from the
beginning of the file. Some tools (python and zipinfo) are able to
read zip files with arbitrary prefixes, but others (libziparchive and
zipdetails) fail.
So pass the file to prefix onto the zip file into merge_zips so that we
can set the offsets from the real start of the file.

Gold uses two PT_LOAD programs: RX, RW
LLD is using three PT_LOAD programs: R, RX, RW
All non-static host bionic executables are linked with LLD, as it's
required in order to embed the linker. The dynamic linker is considered
a static executable for this definition.
When the linker had been built with Gold, we inserted the the RX&RW
loads in the middle of the executable's readonly load, splitting the R
load into two. When this happened, all of the linker's loads existed 1:1
in the final executable.
Now that the linker is built with LLD, we're inserting the loads into
the same place, but LLD merges the first part of the executable's R load
with the linker's R load, so there's not a 1:1 matching.
So just make sure that all of the linker's loads are contained within
the executable's loads (and with the appropriate flags).

Move the actual per-product builds out of the main function, combining

This adds a new status package that merges the running of "actions"
(ninja calls them edges) of multiple tools into one view of the current
state, and gives that to a number of different outputs.
For inputs:
Kati's output parser has been rewritten (and moved) to map onto the
StartAction/FinishAction API. A byproduct of this is that the build
servers should be able to extract errors from Kati better, since they
look like the errors that Ninja used to write.
Ninja is no longer directly connected to the terminal, but its output is
read via the protobuf frontend API, so it's just another tool whose
output becomes merged together.
multiproduct_kati loses its custom status routines, and uses the common
one instead.
For outputs:
The primary output is the ui/terminal.Status type, which along with
ui/terminal.Writer now controls everything about the terminal output.
Today, this doesn't really change any behaviors, but having all terminal
output going through here allows a more complicated (multi-line / full
window) status display in the future.
The tracer acts as an output of the status package, tracing all the
action start / finish events. This replaces reading the .ninja_log file,
so it now properly handles multiple output files from a single action.
A new rotated log file (out/error.log, or out/dist/logs/error.log) just
contains a description of all of the errors that happened during the
current build.
Another new compressed and rotated log file (out/verbose.log.gz, or
out/dist/logs/verbose.log.gz) contains the full verbose (showcommands)
log of every execution run by the build. Since this is now written on
every build, the showcommands argument is now ignored -- if you want to
get the commands run, look at the log file after the build.

Fixes issues on some machines where the socket in TMPDIR ended up with a

/proc/self/fd/#/<file>, or manually creating a similar symlink in /tmp.
Also fixes some issues on Mac where os.Executable returns the symlink
instead of the underlying file, sending a message over a unix domain
socket will block if the reader isn't reading, and sandboxing was
preventing us from running `ps`.

This will allow us to track (and eventually limit) the commands that the
build references via $PATH. These are mostly implicit dependencies on
the host system -- for Linux, we assume something similar to Ubuntu
14.04 with a few extra packages, but this will let us better define
that.
This will not catch uses of tools with absolute paths (/bin/bash, etc),

If a static android library lib1 has static_libs: ["lib2"] then the
R.class files for packages in lib2 will be merged into the jar for
lib1. If an app has lib1 in its static_libs it will get the R.class
files from lib2 through lib1, instead of regenerating the R.java
files with numbering that matches the resource table of the app.
Pass transtive static android library dependencies on the aapt2
command line so that aapt2 will always regenerate the R.java
constants for those packages.
Also extract the packages that have R.java files after each aapt2
invocation. This is not necessary for Soong, but is passed to

The make javac rule uses [ -s srcjar-list ] to decide whether or
not to run javac. zipsync was putting a trailing "\n" in the
list file, so the file was never empty. There was one case of a
package that contained no source files (so java-source-list was
empty) and had a res directory with an xml file that declared no
resources (so aapt.jar was created but empty). The 1-byte
srcjar-list file caused javac to run and error with:
javac: no source files

extract_srcjars.sh uses zipinfo and unzip, which fail with an
error on an empty zip file. Instead of trying to hack around
this (which is hard to make guarantees for since they are
non-hermetic host tools), replace them with a go tool to unzip
a set of zip files into a directory.

Each Python module will generate a zip file containing source & data
files. The Python binary will collect all its dependencies and use
merge_zips to merge each zip file to create a final .par file.

Allow native modules to specify use_version_lib, which will make
an android::build::GetBuildNumber() function available. For host
builds, the function will return the build number at the time that
the module was linked. For device modules it will return the
value of the ro.build.version.incremental property.

Test: m build_version_test && touch build/make/core/Makefile build/soong/cc/libbuildversion/tests/build_version_test.cpp && m build_version_test shows different build numbers for binary and library tests.

Parse the machine-specific symbol tables into a custom symbol table
object and use a single function to find the offset and size of the
symbol in the custom table. Make the functions to convert a
machine-specific symbol table into the custom table also take mocks,
and provide functions to dump mocks from real files. Add tests
that take the mocks and verify they produce the right offset and
size.

Some exe files have a .data symbol at the same address as the
soong_build_number symbol. If the .data symbol is after
soong_build_number in the symbol list, symbol_inject would think
the end address was the same as the start address, and use
uint32(-1) as the size.
Use sort.Search to find the first symbol whose section number is
the same as the target symbol, but whose address is higher than
the target symbol.

macho symbol table entries are not always in order, which breaks
finding the next symbol to find the size of the target symbol.
