Remove some unused historical files.
Aggressively disable warnings to keep the lemon source
pristine and avoid the maintenance burden for lemon itself.
Lemon has its own lax policy for warnings that doesn't match our
own and they won't accept external patches to remove the
warnings, so just ignore them. Lemon is just executed to generate
code for the Wireshark build and the minor code issues it has
have no influence at runtime.
For lemon generated code we selectively disable some linting
warnings.
Remove patches for lemon and lempar, they are no longer required
with these changes to silence warnings.
When cross-compiling wireshark the lemon tool should be built
using the host machine compiler to be run on the host. Before
cmake this was done via autotools CC_FOR_BUILD but cmake only
supports one compiler toolchain per build and requires some
workarounds like running cmake twice using separately defined
toolchains.
This gets ugly and complicated fast when considering multiple
toolchains, especially for a simple tool like lemon, so just
allow builds to override the C compiler and wipe the cflags.
This way systems like Gentoo/ChromeOS/Yocto with a properly
setup cross-compile environment can just point to the native
BUILD_CC or similar while minimizing complexity.
The COMPILE_OPTIONS source file property was introduced with CMake 3.11,
disable warnings via a target property instead (available since 2.8.12).
Disable some VS Code Analysis warnings. These flags seem to be accepted
since VS2015, so they can be added unconditionally.

Changes:
- Drop the old basename modification that was present in the Wireshark
version of lemon.c. Use a new option available since 2018-04-20
("Add the -dDIRECTORY command-line option to LEMON.")
- Redo the static analyzer warning fixes, identifying the root causes
and adding assertions instead of hiding code with __clang_analyzer__.
- Ignore compiler warnings instead of adding config.h, _U_, extra const
keywords, unsigned/signed changes, etc.
- Remove lemon.html, it is out-of-date and external links are available.
In order to make future updates easier, document the exact steps that
were followed to create the lemon.c and lempar.c files. Future changes
SHOULD follow the same process.
My process to reach this updated lemon version:
1. Identify previous sync. Found v2.5.2rc0-147-g653af0f6d0 ("lemon: Sync
with latest trunk.") which seems based on sqlite commit 2b3d584ffe.
2. Check successive Wireshark patches. Identified many non-functional
changes to silence compiler warnings and static analyzer issues.
Found one feature (basename) that can be replaced with upstream -d.
3. Write minimal patches and document changes.
Upstream typos and coding style issues (other than trailing whitespace)
were deliberately not fixed to remain as close as possible to upstream.

Except for the one directory that (currently) has "not yet clean" files,
epan/dissectors, we don't need a separate variable to keep track of the
"clean" source files.
In the cases where not all files were in CLEAN_FILES, put them into the
variable used to enable -Werror or its equivalent.

Autotools has the very useful feature by design of allowing the user
to override the default build flags (you break it you keep it).
Apparently CMake applies COMPILE_OPTIONS target property after
CMAKE_{C,CXX}_FLAGS so that doesn't work here. Prepend our flags to those
variables instead to make it work then.
Specific target flag overrides can still be added with COMPILER_OPTIONS
(e.g: generated files with -Wno-warning) but this is less effective and
then we're back at the point where this overrides user flags. It's less
of a concern though.

If ASAN is enabled, use "-fno-sanitize=all" when building lemon. This
keeps us from having to set ASAN_OPTIONS=detect_leaks=0 in the

Instead of checking for the boolean "FALSE", just set an empty string.
This avoids the need to check for WERROR_COMMON_FLAGS before using it.
The transformation is the same for all files, remove
"if (WERROR_COMMON_FLAGS)" and "endif()", reindent and add quotes (since
we have a string here and not a list).
Modelines have been added where missing.

Setting our compiler warning flags in CMAKE_C_FLAGS does not allow
using different flags per target.
Allow for that possibility by setting the internal WS_WARNINGS_{C,CXX}_FLAGS
and using the COMPILE_OPTIONS property to set them.
This change is just setting mechanism and there should be no difference
in generated warnings.
The check_X_compiler_flag cmake test is changed to test each flag individually.
We need a list, not a space separated string, and the aggregate test is not
significant.

We haven't compiled C++ code with -Wshorten-64-to-32 for quite
