Fix strict warnings, more testing.

The upgrade class is getting pretty heavily reworked, but I still expect it to
work the way it did previously, except for the change from XML to INI.
Code coverage, minor changes, upgrades work
Fix test based on timezone

Ensure the timezone for the database is the same as the timezone for the server
Fix DB tests for differing timezone
Merge branch 'development' of github.com:crazedsanity/cs-webapplibs into development

  Fix test based on timezone
Fix constructor to match parent class
Changes to cs_lockfile for consistency + testability

 * constructor requires path as 1st argument
 * lockfile name is optional 2nd arg, defaults to "upgrade.lock"
 * uses InvalidArgumentException unless path is directory with +rw
 * get_rwdir() is simpler: ensures this->rwDir is a directory then returns it
 * get_lockfile() returns full path to lockfile
 * set_lockfile() doesn't bail when passed name & new name are the same
 * is_lockfile_present() concatenates rwDir + lockfile instead of calling get_lockfile()
Changes to cs_sessionDB for testing

 * use "self::$runDate" instead of "cs_sessionDB::$runDate" to avoid issues if class name changes
 * is_valid_sid() doesn't bail when passed $sid is < 20 characters long: this caused tests to fail, even when they shouldn't have
 * better error checking on doInsert
 * sessdb_gc() overhauled to be simpler/straightforward (still needs work)
 * exception_handler() tests for cs_backtrace() before calling it
 * ignore flogger() for test coverage
Changes to cs_webdbupgrade for testability + stability

 * allow passing of "rwDir" to constructor
 * is_lockfile_present() sets RWDIR before creating a new cs_lockfile
 * don't create/reset cs_lockfile object in reconnect_db()
 * remove unnecessary/redundant create_lockfile() method
