Changed the format of the historical callmap to be plain signature list,
as it isn't really a delta file and renamed the file to not be confused
with deltas.
Added a test to ensure entries in main callmap have history.
Convert deltafile format to new style proposed by weirdan
Modify CallMapTest to use new format
Modify InternalCallMapHandler to use new format
Move assertions to base testcase
To prevent similar errors, add baseline file with signatures pre-7.1, to help verify delta files are correct.
Modify test to use this to detect missing 'old' entries
- Fixed inconsistencies in callmap delta files (mainly 8.0)
- Added several missing changes in the bc_* functions
- Added several missing changes in the mb_* functions
- Added several missing changes in the xml_parser_* functions
- Fixed several issues with sodium_ functions
- Removed all but one of the date_* functions. All were marked as having lost the option to return false, despite this only being true for date_format
