This replaces all of the Apache blurbs at the start of each file with an
`# SPDX-License-Identifier: Apache-2.0` string. It also fixes existing
uses to be consistent in capitalization, and to be placed above any
copyright notices.
This removes nearly 3000 lines of boilerplate from the project (only
python files), which no developer cares to look at.
SPDX is in common use, particularly in the Linux kernel, and is the
recommended format for Meson's own `project(license: )` field
Since the previous commit allows for more scenarios with name
collisions, it makes sense to expand the compile command so that it can
also take into account suffixes. i.e. meson compile -C build foo.exe can
now work if the executable has an exe suffix along with being named foo.

This has no actual effect on the codebase as type checkers (still)
support both and negligible effect on runtime performance since
__future__ annotations ameliorates that. Technically, the bytecode would
be bigger for non function-local annotations, of which we have many
either way.
So if it doesn't really matter, why do a large-scale refactor? Simple:
because people keep wanting to, but it's getting nickle-and-dimed. If
we're going to do this we might as well do it consistently in one shot,
using tooling that guarantees repeatability and correctness.
Repeat with:
```
com2ann mesonbuild/
```
We need to remember its value when reconfiguring, but the Build object
is not reused, only coredata is.
This also makes CLI more consistent by allowing `-Dvsenv=true` syntax.

This finds uses of deny-listed functions, which defaults to map and
filter. These functions should be replaced by comprehensions in
idiomatic python because:
1. comprehensions are more heavily optimized and are often faster
2. They avoid the need for lambdas in some cases, which make them
faster
3. you can do the equivalent in one statement rather than two, which
is faster
4. They're easier to read
5. if you need a concrete instance (ie, a list) then you don't have
to convert the iterator to a list afterwards
This command is magical and I hate it. Mostly because it seems people
have no clue what it does, and what it doesn't do.
Provide informational messages to the user indicating how it works, e.g.
for debugging. Point out if we ran vsenv before shelling out to the
backend.
In commit 928078982c a good error message
about the directory not being a valid build directory, was replaced by a
worse message.
In commit abaa980436 the error message was
replaced by a traceback when trying to load the coredata before checking
if it was a build directory.
Revert back to using the helper function with the good error message.
Reorganize code so that we check basic things first, and do less work
before detecting errors.
Fixes#9584
meson compile itself doesn't permit GNU-style argument permutation, i.e.
TARGET to precede options, so why should we expect ninja to?
And indeed, ninja doesn't document support for this -- but it does
accept it anyway, which is confusing and results in people thinking it's
"supposed to" work.
However, if NINJA=samu then this is in fact enforced. samu does not
permit GNU-style argument permutation. As a result, the arguments passed
to mcompile are actively re-ordered before being passed to the
subprocess, and samu dies with a fatal error.
Fix ordering in mcompile.py and add a comment to warn future readers
that the order does, in fact, matter.
This patches takes the options work to it's logical conclusion: A single
flat dictionary of OptionKey: UserOptions. This allows us to simplify a
large number of cases, as we don't need to check if an option is in this
dict or that one (or any of 5 or 6, actually).
The ninja path is already logged as part of configure. Logging it
again every time when using meson compile is overly verbose and
doesn't add much value for the user.
I wrote this to convert run_tests.get_backend_commands() over to the
new meson wrappers, but that turned out to be harder than I expected,
so just splitting this out for now.
This allows the NINJA environment variable to support all the Windows special
cases, especially allowing an absolute path without extension.
Based on a patch by Yonggang Luo.

This matches `meson test`, and there's really no other meaning that
could be attributed to this, since you would call `meson` to get the
version, not the `compile` sub-command.
