callgrind identified check_viewport and scan_int as pretty hot code paths on startup
and playback
check_viewport uses strlen to check the string has at least 4 characters
we can just check if str[3] != '\0' without walking potentially much further
and no function call..
scan_int was building a buffer for atoi to parse when we can just do it in the loop
directly

since we now have the length of tag names thru the param_pos var
we can simplify the find tag function to skip if the length doesn't match
this allows us to no longer make a string copy in order to terminate
the buffer
move some of the more frequently encountered tags to the top of the
lookup list
only SKIN_TOKEN_UNKNOWN position matters as its empty string is used
as the sentinel

skin_tags have name and sometimes valid parameters
storing a pointer results in a lot of wasted space
instead record size of name and write the parameter string just after

If any of those functions should be (unused) API functions,
they can easily be turned back once really needed.
Detected using a new cppcheck check that
uses the internal symbol database to catch
functions that are only used in the current file.

The parser was unconditionally scanning things which it thought
were conditional/enum lists (or tag arg lists) when they couldn't
possibly be (i.e < inside a param which should be valid).
This change fixes it (i.e %?and(%if(%pv, <, -50), %if(%mp, >i, 1))
is perfectly valid now.
This *may* break your exsiting skins if you were using %if with < or >

This reverts commit ec8b21eef8b2fe1bd02f335dbc0dfbf05c2deff2 which was pushed by accident.
