Sebastian f0646d3754 checkunusedfunctions.cpp: Fix files.txt parsing (#1197)
On Windows searching for the last colon finds the colon which is part of
the path of the source file (e.g. "C:/projects/a.cpp"). Thus the path is
saved incomplete. This fix searches for the second instead of the last
colon and uses the data after the second colon as the path of the source
file.

Move a corresponding sanity check so that less assignments could be
performed eventually.

rebnridgway 995b496ddf Add suppressions to the XML dump (#1166)
* Added parsing suppressions from dump xml.

* Added code to dump suppressions to an xml file

* Added declaration for dump function

* Suppressions will now be written to the xml file when a dump is requested

* Fixed syntax error

* Removed excess whitespace

* Fixed indentation to be consistent

* Fixed indentation to be consistent

* Fixed indentation to be consistent

* Added missing include for ErrorLogger::toXml

* Fixed suggestions from pull request #1166

Switched to using ranged for loop to iterate through suppressions.
Made the line number attribute optional, rather than 0 if not specified.  This means when Python deserialises it it will be None, which is more pythonic.

* Implemented checking suppressions in reportError

This modification expects suppressions and a function to be called to write a line of output to be passed in.  The function checks if any of the suppressions match the warning (with the new Suppression.isMatch function) and if so returns None.  This change maintains the old behaviour of returning the warning text, but adds the possibility of returning None if the warning was suppressed.

* Fixed code quality warnings

* Removed more extraneous whitespace

In 9cea2d6df, simplifications were removed for a number of functions
which should instead be handled with configurations. The commit did
however not update the description of the function, do this now.

Also sin() and sinh() and their float and long double versions were
missing from the comment so add these as well.
