Several changes:

 - Wt 4 specific:
  - PostgreSQL: fixed date/time (de)serialization
  - Fixed duration binding/retrieving for Sqlite
  - Don't use gmtime, just use date library in MSSQLServer
  - std::unique_ptr<SqlStatement> instead of raw pointer
    where appropriate
 - Merges from master:
  - Finalized release date for 3.3.8
  - Wt::Dbo: alias every column retrieved
  - Fixed SQL Server static linking issues
  - Fixed issue where image preloading could break incremental updates
  - Merged Microsoft SQL Server support for Wt::Dbo
  - Fixing and simplifying count query so it's always correct
  - SQL Server: using bigint for duration, time is limited
    to time of day
  - Dbo: Added test for long and negative durations
  - Dbo: Use quoted strings in tests for Firebird
  - MySQL backend: properly store negative durations
  - MySQL: set utf8mb4 for proper UTF-8
  - Removed left over stuff from headers() implementation
  - Disable isVisible() check for now
  - Documented that in _some_ cases it's fine not to call beingDeleted()
  - Issue #5809: added missing beingDeleted() calls
  - Add missing <sys/select.h>
  - Issue #5873: Linking with WT_SOCKET_LIBRARY necessary when including WIOService
  - Issue #5815: emit input signal when line edit changed (if we have an input mask)
  - Fix issue where submenu of popupmenu's signals are not exposed
  - Stop propagation of starttouch/endtouch on menu items so we don't get a document touch
    This fixes a problem with Safari on iOS where the menu was closed after
    checking/unchecking an item, causing the item to not be checked/unchecked.
