* dump: Fix concurrency problem with dump files
This adds the process ID for the cppcheck process to the filenames
of the .dump and .ctu-info files that the process generates.
So
lib/cppcheck.cpp.dump
becomes
lib/cppcheck.cpp.<PID>.dump
For example:
lib/cppcheck.cpp.2637871.dump
The reason for this change is that if there is a buildsystem which
supports concurrency, multiple instances of cppcheck may be run for
the same file. For example, if the same file is compiled in multiple
build variants, or for multiple targets.
If running the MISRA plugin over such a project with concurrency
enabled in the buildsystem, the plugin ends up crashing as multiple
jobs attempt to create/trample/delete the same files while other
jobs are using them.

* dump: Include pid in filename if dump not explicit
Only change the dump and ctu-info filenames to include the PID if
they are being generated due to an addon.
This means that existing scripts that use `--dump` will still work
if they depend on the previous naming behaviour. The more robust
filenames containing the pid will be used when the dump files are
used as an internal implementation detail for passing data to addons.
However this means that anything that does explicitly use `--dump`
will be susceptible to concurrency problems.
* test: Update addon dump file test to account for pid
This test causes a dump file to be created by enabling the misra
addon. Since the dump files now include the cppcheck process pid
this test had to be updated to account for the change.
* std.cfg: added support for `std::unordered_map::count()`
* std.cfg: added support for `std::multimap::count()`
* std.cfg: added support for `std::unordered_map::insert()`
* std.cfg: added support for `std::unordered_set::insert()`
* std.cfg: added support for `std::unordered_set::emplace()`
* fixture.h: added TODO
* TestPlatform: improved tests for built-in platforms
* TestPlatform: changed tests to TODO asserts
* testfilelister.cpp: added TODO
* fixture.h: added `PLATFORM` macro to load platform / use `PLATFORM` in tests
* platform.h: corrected capitalization in `Platform::platformString(PlatformType)` and bail on unknown type
* fixture.h: fixed `readability-redundant-string-cstr` clang-tidy warning
* testplatform.cpp: fixed `functionConst` selfcheck warnings
* Added cfg information about std::span
* Add tests for span handling
* Add details about functions and tests fo std::span
* Add tests in dangingLifetimeContainerView for span
* Reduce c++ version from 20 to 2a
* Add checking if span is supported in std lib cfg checks
* Add try_retry-logic to get_packages_count()
Occasionally, get_packages_count() fails, which is a bit annoying since
it happens after compilation and therefore can take some time to detect.
Add try-retry to the function to make it more robust.
* Move try_retry-logic to lib.get_package()
Moving it to the library means test-my-pr also benefits from it. This
fixes Trac ticket #11405.
