For LDML keyboards this change fixes the `emit_key` flag so that it has
the same value for the KeyDown and the KeyUp event. This fixes some
problems with stuck keys. Previously we would set `emit_key=TRUE` on
KeyDown but `emit_key=FALSE` on KeyUp for frame keys. This caused Linux
to never see the KeyUp event, resulting in a stuck key.
Also add unit tests that verifies that the actions that we get after
calling `km_core_process_event` are what we expect.

This replaces and enables the commented `k_000_null_keyboard` test which
didn't work because keys that are not on any layer don't produce output.
This instead defines a minimal keyboard with just two keys and then tests
typing a key that is on the keyboard followed by a key not on the keyboard.

Production code uses a list of context items, so this change modifies
the tests to also use a list instead of a vector to more closely match
production code.
Addresses code review comment.

This change replaces the reverse iterator loop that holds a stale iterator
across `pop_back()` calls with a pattern that directly accesses
`context.back()` on each iteration. This avoids undefined behavior from
iterator invalidation when mutating the list or vector.
While so far the previous code didn't show problems, it might still access
released memory depending on the implementation. The documentation for
`pop_back()` says "References and iterators to the erased element are
invalidated", so the previous implementation was clearly wrong.

When normalizing, we need to stop processing on an NFC boundary, not an
NFD boundary, to support normalizations such as in Bengali, where
appending `U+09D7` to a context of `U+0995 U+09C7` should result in
`U+0995 U+09CC`.
The specification is unclear on this; see https://unicode-org.atlassian.net/browse/CLDR-19218
This also updates the ldml keyboard unit test suite to support running
in full NFC mode (used in all Engine implementations) as well retaining
the NFD mode (now only used by the debugger).
Side note: the Bengali normalization failure case was picked up by the
improvements to the unit test suite, proving once again that good tests
are so valuable.

Ensure that when a single backspace decomposes the last NFC character in
the app context, the remainder of the 'cluster' is preserved, matching
the implication of the CLDR keyboard specification.
This addresses the behavior in #15487 where the cached context became
out of sync with the app context after deleting an entire NFC cluster
such as ê, which caused a loop ending up with the entire context being
deleted, at which point the loop exited with a fail-safe.
Note that the LDML keyboard tests (ldml.cpp) do not currently exercise
the normalization code; this is a gap that should be addressed to ensure
that we are testing final application behavior.

Build all the .kmx files used for kmn and ldml unit tests in batch
rather than one at a time. The ldml-test-data builds remain unbatched
for now (and are visibly slow!).

- improve an output string
- catch BMP noncharacters besides U+FFFF (H/T @mcdurdin - this was the whole point of the PR) plus test

- improve how validation works - a missing section does not mean an invalid section. distingush these.
- propagate errors for invalid sections
- update documentation of required sections
Fixes: #9446
- turn off some asserts- makes untestable
(there are asserts at 'higher levels' such as loading the entire kmx+)
- add a test with a synthesized COMP_KMXPLUS_STRS - a valid and an invalid one
Fixes: #9446
Add 4 test keyboards to validate `nul` and `if` used in conjunction with
`index` and `context` and corresponding references in core unit tests.
Add a script to rebuild baseline keyboards using a copy of kmcomp.exe
16.0.138; this is setup and tested only on Windows (YMMV on WINE, etc).
Add the 4 additional baseline test keyboards to kmcmplib unit tests for
build consistency between kmcomp 16 and kmcmplib 18 (all pass).
Note: two of the new Core tests currently fail. This is expected, see
issue #13304.
Fixes: #13303
- yes, expand 'other' to all possible combinations
- use ALT and CTRL instead of RALT,LALT and RCTRL,LCTRL in the key list (reduce expansions up to 4x)
Fixes: #12298
Had a real yak shave this morning with disabling assertions in release
builds in our C/C++ code. It turns out that our unit tests use
`assert()` which we intended to use from `test_assert.h`, but in some
cases `cassert` or `assert.h` had been #included after `test_assert.h`,
overriding our special `assert()` macro. The chain of includes is
somewhat hard to puzzle out -- it's often buried several levels deep.
This meant that a release build would drop all test assertions, meaning
most tests passed, unsurprisingly, as there were no assertions left to
fail ... but some tests failed with crashes because we optimized out
important lines such as `assert(some_important_function())`.
I was quite unhappy with this fragility, so I have opted to rename
`assert()` to `test_assert()` in all of our home-grown C/C++ unit tests,
which further highlighted unit tests which were only using the C/C++
`assert()` and not ours, so then had to figure out which unit test
executables needed to have `test_assert` added, and then ... then ...
discovered a bug in `test_color.h`, where we were #including
`io.h`/`unistd.h` inside a `namespace console_color {}` block, which
just happened to be the first ref to those beautiful headers, and thus
(because `#pragma once`) meant that useful little functions like
`access()` were no longer accessible to us in the global namespace.
I have also audited Every Single Call to `assert()` to verify that we do
not do Important Work inside the parentheses, and, apart from those
offending unit tests, now resolved with `test_assert()`, it looks like
all is good.
I would like to present one very well-shaved yak in this commit.

- split keyboard loading into loading KMX file into blob and then
loading the keyboard processor from the blob.
- deprecate `km_core_keyboard_load`
- move file access next to deprecated method. This is now the only place
that loads a file in Core; unit tests have some more places that
load files.
- introduce GTest and add unit tests for loading from blob
