By using the PartialConfigEnvironment, the clients of buildconfig will
depend on config.statusd/ files instead of config.status directly.
Clients can access substs and defines using buildconfig.substs['FOO'] or
buildconfig.defines['BAR'], and then collect file-level dependencies for
make using buildconfig.get_dependencies(). All GENERATED_FILES rules
already make use of this because file_generate.py automatically includes
these dependencies (along with all python modules loaded).
As a result of this commit, re-running configure will no longer cause
the world to be rebuilt. Although config.status is updated, no build
steps use config.status directly and instead depend on values in
config.statusd/, which are written with FileAvoidWrite. Since those
files are not official targets according to the make backend, make won't
try to continually rebuild the backend when those files are out of date.
And since they are FileAvoidWrite, make will only re-run dependent steps
if the actual configure value has changed.
As a result of using JSON to load data from the config.statusd
directory, substs can be unicode (instead of a bare string type).
generate_certdata.py converts the subst manually to a string so the
value can be exported to the environment without issue on Windows.
Additionally, patching the buildconfig.substs dict no longer works, so
the unit-symbolstore.py test was modified to patch the underlying
buildconfig.substs._dict instead.
The other files that needed to be modified make use of all the defines
for the preprocessor. Those that are used during 'mach build' now use
buildconfig.defines['ALLDEFINES'], which maps to a special
FileAvoidWrite file generated for the PartialConfigEnvironment.

This removes the dependency on config.status for CONFIGURE_DEFINE_FILES.
Instead, each file depends on the specific configure values that it
uses.

The config.statusd directory is created alongside config.status, which
contains the same information but is split across many files instead of
all in a single file. This allows the build system to track dependencies
on individual configure values.

There's currently a function for getting added files (A) and modified files
(M). We'll also eventually need the ability to get deleted files (D) and any
combination of the above, e.g (AM). Rather than creating a new function for
each possible case, let's have a single function where you can pass in which
modifiers you are interested in. With this patch, if you want all modified and
added files, you can do:
get_changed_files('AM')
By default 'ADM' is used.
This also adds a 'mode' option for git. This allows consumers to return staged
files, unstaged files or both. The default ('unstaged') keeps the current
behaviour in tact.

Technically this turns on gnu++14. I encountered a few errors when using c++14:
1) _USE_MATH_DEFINES needed to be defined for MinGW
2) MinGW did not define _finite under c++14
3) MinGW's float.h did not define Microsoft specific float functions under c++14
All of these were because c++14 defines _STRICT_ANSI_ which MinGW obeys and
avoids defining certain functions. The first two could be patched around, but
the third was a blocker, so we switched to gnu++14

Unfortunately this also needs to be kept in Makefile.in to handle
other consumers of INCLUDES while we transition them.

The code for obtaining a BuildReader for evaluating moz.build files
is generic and non-trivial. We already had a custom implementation
for `mach file-info` that implemented support for Mercurial
integration. Bug 1383880 will introduce a second consumer.
So this commit factors out the "obtain a BuildReader" logic into
a reusable function on our base MozbuildObject class. This makes
it easily available to various parts of the build system and mach
commands.
As part of the change, we detect when ``.`` is being used as the
revision and verify the working directory is clean. This behavior
can be disabled via argument if unwanted. But it's useful by default
to ensure consumers aren't expecting to read uncommitted changes.

It seems reasonable to expose this outside of the BuildReader.

To construct an empty set, we need to use the `set()` notation. In order
to do that, we need to expose `set` to the moz.build sandbox.

This ensures we use forward slashes, even if Mercurial emits
backslashes (which it can do on Windows).

These tests weren't running in automation because hglib wasn't
available. An upcoming commit will vendor hglib. This exposed that the
tests can fail if ui.username isn't set.
In this commit, we introduce a helper function to obtain an hglib
client with ui.username set. We also convert tests to use the context
manager form of the client so resources are cleaned up immediately
without relying on refcounting or garbage collection.
