Section suffix is the decimal ASCII value, not the character itself.

not just 'settings'

Fix issue 439. Thanks Nelgin!

'execution_ars' not 'run_ars'.

Cut the load/parse time of large (e.g. 1MB) .ini files in half.

Performance optimization: each section becomes its own separate (named) string list, so repeated searches through all the lines (including keys/values) are eliminated.

This optimization resulted in a 50% reduction in time to load/parse large .ini files into memory.

An additional 10% improvement was observed by freeing/nulling section names as they were consumed. Setting them to blank strings was also tried (without immediate freeing), but no performance improvement was observed.

For use with some new ini_file functions.

Some way for the sysop to specify their defaults would be preferable.

Use 'inipath' instead.

Fixes msgs.ini disappearing issue as reported by Nelgin

format ‘%lX’ expects argument of type ‘long unsigned int’, but argument 3 has type ‘uint’

Resolve warnings and issues with ambiguity around the size of a long int.

Just to help resolve some warnings in scfg*.c

long is the one type that a different size between the supported 32-bit and 64-bit platforms, avoid its use.

Don't use long types in parameters to/return types of non-long functions (e.g. *Integer(), *Bytes(), *HexInt()): use int/uint instead. long is the one type that is a different size between the supported 32-bit and 64-bit target platforms, so avoid its use here.
*LongInt() functions now accept/return long, not ulong.
*ShortInt() functions accept/return short, not ushort.
Added *UInteger, *UShortInt(), *ULongInt() functions for dealing with unsigned integer values, specifically.
Add bit-width-specific aliases to integer value functions: *Int16, *UInt16, *Int32, and *UInt32

Some re-arranging of lines to group section keys together, logically.

Fixed typos with "newuser" vs. "nweuser" section naming.

Need to nullify the xpms after destroying/freeing (as is done in other
servers already).

By using the new iniCutSection() function primarily, parse and consume
each .ini file section, reducing the search area (ini content/list) for each
section consumed.

The use of iniFreeStringList() intead of strListFree() appeared to have some
benefit to performance as well, likely due to a DLL heap dance.

This brought the file.ini file loading on Vertrauen (8518 lines) down from 10+
seconds (on Windows over SMB/1Gb link to a Samba sever) to less than one scond.

iniCutSection is like iniGetSection except that the section is is also
removed from the ini content list. For performance reasons, the list is not
realloced (maybe saving memory), and for this, I added iniRemoveSectionFast.

For cases where an .ini file may contain many sections and keys, it can be
a huge performance improvement to remove the sections as they are parsed
(i.e. use iniCutSection instead of iniGetSection), thus reducing the number of
operations required for subsequent section/key searches (each call to iniGet*).

This change was required to make the new ctrl/????.ini file loading
(scfglib*.c changes) acceptable on Vertrauen, Windows builds.
