Instead of using the number of processors in the host, use the number of
processors available to the process, respecting cpu affinity
assignments. Without pthreads, fall back and use the number of
processors in the host as before.
This is now applied everywhere so runing `nuamctl -C 0-3 verilator` or
`numactl -C 0-3 Vsim` should behave as if the host has 4 cores (e.g.
like in CI jobs)
Added cppcheck-suppressions.txt in the repo root. You can add new
patterns in there instead of having to parse the XML output.
Also configure to add the -D__GNUC__ preprocessor macro, which makes it
understand UASSERT (it understands the 'noreturn' function attribute).
Added some case by case specific suppressions and fixed up other code,
especially in V3Ast*h and V3Dfg*.h, including code generated by astgen
that had some no-ops that irks cppcheck.
One thing it does not seem to like is `const` class members with default
initializers in the class. It will assume that's always the value, even
if overridden in the constructor. We had few so removed them.
With that a lot of files in `src/` are now clean or only have a handful
of issues. Therefore, I have also deleted cppcheck_filtered, and made it
produce human readable output straight to the terminal.
Regarding cleaning up the reported nits, I kind of got bored after
V3[A-E] so pausing here. Apologies for the merge conflicts.
Tested with cppcheck 2.13.0
* Internals: Move getenvStr to verilatedos. No functional change intended.
* Fix POS34-C. Do not call putenv() with a pointer to an automatic variable as the argument.

Add a new data-structure V3DfgCache, which can be used to retrieve
existing vertices with some given inputs vertices. Use this in
V3DfgPeephole to eliminate the creation of redundant vertices.
Overall this is performance neutral, but is in prep for some future
work.
* Ignore CLion project files and CMake outputs
* Supporting stripping file path that contains backslash
* Set /bigobj flag and increase stack size for windows platform
* Fix MSVC warnings
* Add VL_ASSERT_CAPABILITY; add assumeLocked and pretendUnlock to V3Mutex.
* Pass jobs as template-arguments and use std::packaged_task.
* Add and use V3ThreadPool::ScopedExclusiveAccess.
