Gcc does not support `x c*-header` when using `-` as input filename,
which is what ALE does.
Rework the feature to only use `-x c*-header` flag when using Clang and
not GCC.
The feature is now also controlled with the variable
`g:ale_c_cc_use_header_lang_flag` and
`g:ale_cpp_cc_use_header_lang_flag`.
When linting an header file in C or C++, `-x c-header` or
`-x c++-header` should be used instead of `-x c` or `-x c++`.
Using `-x c` or `-x c++` for headers files can lead to unused variables
and functions marked as static inlined as seen in #4096.
Using `-x c-header` or `-x c++-header` solve these issues.
The list of file extensions that are considered as header files can be
configured with the variables `g:ale_c_cc_header_exts` and
`g:ale_cpp_cc_header_exts`.

The test was checking the wrong directory.
Users can easily be confused when they set some options for a C or C++
compiler, and another compiler is run with different options, which
still reports errors. To remedy this, the existing `gcc` and `clang`
linters have been replaced with a `cc` linter that will run either
compiler.
This is a breaking change for ALE v3.0.0.
The options for parsing `make -n` and `compile_commands.json` flags
are now enabled by default, so people can start getting better flags
for their files by default.
`compile_commands.json` flags are now preferred over `make -n` results,
to make the options work better by default.
The existing option setting handles setting additional compile flags to
pass to clang-tidy. The new option setting added here allows setting
additional clang-tidy specific flags to be passed as well.
Fixes#2324
* Handle flawfinder severity level
* Reverted code allowing Flawfinder to piggyback off of gcc's format handler
* Gave Flawfinder its own format handler and made requested changes.
* Flawfinder support added for C and C++
A minor modification to gcc handler was made to support flawfinder's
single-line output format that does not have a space following the
colon denoting the warning level. gcc handler still passes its
Vader tests after this modification.
* Documentation fixes
* Revert documentation regression
* Added Flawfinder to table of contents
* Removed trailing whitespace
* Follow ALE conventions better
Added additional documentation and Vader tests
A limited number of clang-tidy checks can be used with C, too. I pretty much
copied and refactored the C++ clang-tidy linter, and added some documentation
about C-compatible checks.
