Aleksandar Fabijanic 1850dc16aa Benchmark and FastLogger (#5081)
* fix(SharedLibrary): Missing DLLs not reported #5069

* fix(CMake): not producing proper binary names #5070

* fix(SharedLibrary): disable shared lib tests in static build #5069

* fix(misc): add pdjson links to gitignore, remove unused var in SharedLibrary, harden TaskManagerTest

* fic(ci): separate oracle and sqlserver odbc (out of disk space) (#5075)

* fic(ci): separate oracle and sqlserver odbc (out of disk space)

* use oracle odbc driver

* use oracle free

* ad db user

* postpone adding user after build

* remove default tablespace (does not exist)

* reinstate all ci jobs

* add postgresl odb tests to ci

* remove spurious syminks

* fix gitignore (pdjson)

* Remove VS projects #5076

* chore: revert leftover ODB IP address

* fix(CodeQL): float comparison alerts

* fix: compile errors

* chore: upgrade asan to macos-14 (tryout)

* fix: .gitignore symlinks; XML Makefile wrong pattern

* Optimize PatternFormatter and Timezone performance #5078

PatternFormatter:
- Cache node name (Environment::nodeName()) to avoid repeated syscalls
- Add extractBasename() for efficient %O format specifier
- Add string reserve(128) to reduce reallocations during formatting

Timezone:
- Cache UTC offset to avoid repeated syscalls (8x speedup for %L patterns)
- Auto-detect TZ environment variable changes to invalidate cache
- Add reloadCache() method for explicit cache refresh

Tests:
- Add TimezoneTest::testUtcOffsetCaching()
- Add PatternFormatterTest::testExtractBasename()

* fix: use Path::separatorin extractBasename #5078

* Add Benchmark #5080

* enh(Logging): move constructors for Message and Logger #5078

* chore(AsyncNotificationCenter): eliminate MSVC warnings

* enh(build): c++20 support #5084

* feat(CppUnit): print class name
execute all named tests (not only the first one)
accept test name with class (eg. testrunner LoggerTest::testLogger) #5083

* feat(Benchmark): Add Logger/FastLogger comparison benchmarks and Windows support

- Add LoggerBench.cpp with AsyncChannel vs FastLogger benchmarks
- Add compare.sh (Linux/macOS) and compare.ps1 (Windows) scripts
- Add LOGGER_BENCHMARK.md with cross-platform benchmark results
- Update README.md with Windows build instructions (Ninja, CMAKE_PREFIX_PATH)
- Add error message when -- options are used on Windows (should use /)
- Update CMakeLists.txt and Makefile to include LoggerBench #5080

* feat(FastLogger): #5078
FastLogger provides a Poco-compatible wrapper around the Quill logging
library, offering significant performance improvements over AsyncChannel
through lock-free SPSC queues and backend thread processing.

Key features:
- Drop-in replacement for Poco::Logger with FastLogger::get()
- Support for all standard Poco channels (Console, File, Rotating, etc.)
- XML/properties configuration via FastLoggerConfigurator
- Thread affinity for backend worker on Linux and Windows
- Log file rotation with size and time-based policies

Performance (CPU time - calling thread latency):
- Linux: 31-70x faster than AsyncChannel
- Windows: 23-87x faster than AsyncChannel
- macOS: Limited improvement due to lack of thread affinity support

New files:
- Foundation/include/Poco/FastLogger.h
- Foundation/src/FastLogger.cpp
- Util/include/Poco/Util/FastLoggerConfigurator.h
- Util/src/FastLoggerConfigurator.cpp
- dependencies/quill/ (header-only Quill 7.5.0 library)

* fix(cmake): disable FastLogger on emscripten (not supported) #5078

* feat(FastLogger): add cpuAfinity config parameter #5087

* fix(FastLogger): Fix lock-order-inversion in FastLogger (TSAN) #5078

* fix(cmake): build not stripping release binaries #5085

* fix(PCRE): fails to compile with clang/c++20 #5131

* feat(AsyncChannel): add CPU affinity property #5087

* feat(SpinlockMutex): make it adaptive #5132

* feat(AsyncChannel): add CPU affinity property #5087

* chore: remove leftover file commited by mistake

* feat(build): allow FastLogger to be fully disabled at build time #5078

Build system changes:
- Add POCO_NO_FASTLOGGER compile definition in CMake when ENABLE_FASTLOGGER=OFF
  to prevent Config.h from auto-enabling FastLogger
- Add ifdef guards around FastLogger tests in LoggingTestSuite.cpp
- Exclude FastLoggerTest.cpp and FastLoggerChannelsTest.cpp from CMake build
  when FastLogger is disabled
- Add POCO_NO_FASTLOGGER support to Make build system for Foundation and Util
- Add CI jobs to verify builds work without FastLogger (CMake and Make)

Code changes:
- Add LoggingConfigurator::configure() convenience method for quick logging setup

* fix(ci): testrunner args

* chore(progen): remove leftover script #5076

* fix(test): give ANC a bit more time to process

* fix(ci): set env before test run

* chore(doc): quill license

* feat(Channel): add log(Message&&) #5133

* fix(ci): set env before test run

* fix(TestRunner): don't search children #5083

* feat: lock-free queues #5134

* feat(Benchmark): various comparisons

* chore: cleanup benchmark
