Tagged cachable SQL query.

Ignore arguments in backtrace saved into the Semaphores table to radically reduce INSERT query size.

Added "SystemLog.LogCodeFragmentsRotated" to the unit config.

• added ability to log code fragments for source file/line
• added code fragment rotation
• added filtering (prevent logging code fragments from non-interesting files)
• fixed notices, when logging code fragments from non-specified files

Found issues (height of the table above the grid is increased with each window resize), when the mode="minimal" attribute on a scroll container is used.

Removed an empty line.

Updated test plan:

Fixed issue, where database cache without expiration had 0 instead of -1 lifetime stored.

Script scanned 50 slab numbers and stopped. Found only this (lines with empty slabs omitted):

keys have "_serials" at the end, so do not match keys from test plan
no other keys with "master" found with other requests

Replicated MemcacheCacheHandler class updates to the MemcachedCacheHandler class.

Detected that after memcache restart, test setCache with $application->setCache('key_with_def_exp', 'v1');, is passed only when twice open index.php. First index.php opening does not set value.

Fixed ArgumentCountError exception on the System Configuration step during clean install on PHP 7.4.

Set infinite expiration for site serial key.

1. write a test plan for:
   • memory cache testing
   • database cache testing
   • template cache testing (via cache_timeout tag parameter, m_Cache tag and similar stuff)
2. store site serial with infinite expiration, because otherwise, it's expiration after 1 month will invalidate the whole cache

1. attempts to extract code from the trace, that doesn't contain a file reference
2. code of the source file/line isn't shown (because it's outside of a trace)

Adding phrases.
