lemon: fix GCC/Clang warnings pre CMake 3.11, silence VSCA warnings 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.

add_executable(lemon lemon.c)
cmake: lemon: allow overriding lemon CC setting 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.

Lemon: Update code and remove cruft 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.

lemon: sync with upstream (2018-09-08) 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 - Remove lemon.html, it is out-of-date and external links are available.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.

cmake: make WERROR_COMMON_FLAGS a normal string 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.
