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.

Searched for new key with command key_memcache_dump.sh key_with

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

Looking for 'key_with' key in 3 slab...

Failed test "Testing internal caches expiration for DB cache" in the part "all other keys have an expiration of 25 days (with a few seconds margin) relative to the time they're set".

Partially tested for Memcached. Failed test with $application->addCache('key_with_exp', 'v2', 3600);

ITEM test [1 b; 0 s]
Failed condition "these keys have infinite expiration (the 1738250904 number might differ on your install)" - given "0 s" is not like some great integer like "1738250904"

some other keys, containing "master", found only with request

(sleep 1; echo "stats cachedump 3 0"; sleep 1; echo "quit";) | telnet localhost 11211 | grep 'master'

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.
