Fixes#7216.
The warning message 0x209A 'The rule will never be matched because its
key code is never fired.' was being generated multiple times for a
single line because the `JavaScript_Key` function it is generated by is
used for various purposes.
This PR keeps a cache of reported key rules to ensure that the message
is reported only once for a given key rule, and also improves the
reporting to clarify which specific key is unreachable, which makes it
easier to diagnose when using `any(k)` style messages, for example:
```
lao_phonetic.kmn (237): Warning: 209A The rule will never be matched for key 'ñ' because its key code is never fired.
```
This also reduces the warning to a hint, as this should not be a
blocking issue for a keyboard, rather just a place the keyboard author
can tidy up.
If `-no-compiler-version` is specified, then we skip the embedding of
the `TSS_COMPILEDVERSION` and `TSS_KEYMANCOPYRIGHT` stores. This is
intended for use with regression test builds of keyboards when we want
to verify changes to the compiler.
This patch introduces the new export `SetCompilerOptions` in kmcmpdll,
which should make it easier to include new options like this in future
versions.
Fixes the release build where we do `nmake symbols` for developer/src,
which was failing on calls to these two sets of components. (In
windows/src, the build structure is different due to an additional layer
of folders, so we end up with no `nmake symbols` call on the common
components).
Note this also drags TextFileFormat.pas and KMDActionInterfaces.pas into
the package so have moved those into general and components folders
respectively, alongside KMDActions.pas and updated corresponding
project includes.
