This change adds a pw_test_server module which implements a gRPC server
for queueing and distributing unit tests across multiple test runners.
The server is implemented as a Go library which can be imported and used
by developers to build a custom unit test running infrastructure.
To use the server, a UnitTestRunner interface that processes requests to
run unit tests must be implemented and registered with the server. An
implementation of this interface which runs unit test executables
through an external command is provided alongside the server.
An example program that uses the server library to run a unit test
server is also provided within the module. This program uses the
command-based test runners to run unit tests on a local machine. It is
configurable through a config file, allowing multiple workers to be
registered with the server. The program additionally doubles as a gRPC
client for the server which can be invoked with the path to a unit test
executable to schedule it to be run.

This change adds a pw_varint module containing functions for encoding
and decoding variable-length integers.

This change introduces the pw_dumb_io module, a module intended for
pigweed testing and bringup. pw_dumb_io includes a facade, and a backend
implementation using stdio (pw_dumb_io_stdio).

This change adds a size reporting module named pw_bloat. The module
uses Bloaty McBloatface to generate size report cards for binaries. It
provides a GN template which defines an action to perform a size diff
on a group of binary targets.
Example output:
simple_bloat

Introduce functions for outputting numbers as strings. Unlike some
snprintf implementations, these functions support 64-bit integers. Also,
very limited floating point support is provided.
These functions are faster than snprintf and never truncate numbers.

This change adds a module which builds documentation using Sphinx.
Documentation files and assets are defined using a pw_doc_group GN
template which lists out all of the sources as metadata. Another GN
template, pw_doc_gen, collects the metadata from pw_doc_group targets
into a JSON file and defines an action that runs a script to build the
HTML docs.
A docgen script is provided by the pw_docgen module. This script reads
the JSON metadata file collected by a pw_doc_gen template, copies all of
the source and resource files into a documentation tree, and runs Sphinx
on the tree to render the docs as HTML.

This change adds two Pigweed modules: pw_preprocessor and pw_unit_test.
The preprocessor module contains header files providing helpful macros
for the C preprocessor. The unit test module contains a starter
implementation of a unit testing framework for Pigweed.

This change adds Pigweed's first few (incomplete) modules: pw_build,
pw_status, and pw_toolchain. The main scaffolding for Pigweed's GN-based
build system is also included, with a root BUILDCONFIG and BUILD.gn file
defining a top-level modules build target.
