Redo 3716933046 but only

Patch lemon to stop parsing options upon encountering "--".
This prevents an issue in the unlikely situation where the
source directory or a source filename has a '=' in it, or
starts with a "-".
This has been reported to sqlite upstream.
Add support for using the host system's lemon binary instead of
compiling our own. Many linux distributions include a lemon
parser generator package. Using this binary when cross-compiling
is much simpler than configuring the build to use the build host
toolchain to compile lemon.
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.
Wireshark fails to build when cross-compiling on Gentoo/ChromeOS
systems because the lemon command is not properly specified or
included in PATH, failing with:
/bin/sh: lemon: command not found
The relevant excerpt from build.ninja is:
COMMAND = cd ..._build/plugins/epan/mate && lemon -T.../tools/lemon/lempar.c
-d. .../plugins/epan/mate/mate_grammar.lemon
By specifying the full path to "lemon" we ensure it is
always searched and found in the correct location.
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- Remove lemon.html, it is out-of-date and external links are available.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.

This generates a top level target, checkAPI, that is
excluded from the ALL build target, so must be run separately.
On Windows using a Visual Studio generator, call

Add a dependency on the lemon binary and lempar.c files because the
output depends on these tools. This is already done for autotools and
nmake.
In addition, clean up the generated .h and .out files.

Note that CMAKE_CFG_INTDIR is no longer necessary for this purpose but
has been left for compatibility with existing projects. Instead
add_custom_command() recognizes executable target names in its COMMAND
So just use "lemon" instead of specifying the full path.

That's what the packages are for, so instead of creating

It's only beginnings, so epan is commented out in

This is more a synch to avoid duplicate work and creating
