[ww-tedit-dev] new functions to store sections in .ini files

[petar marinov]

ini.c holds all the basic functions to store and read config 
information. Presently reading employes the TFile primitives while 
storing is very inflexible -- it uses fprinf(). Using fprintf() means 
that .ini files could only be regenerated as a whole 
(fopen-fprintf-fclose) and won't allow for sections to be individually 
replaced.

It is criticall to remove this barrier for two reasons.

1. Plug-ins must have sane interface to store/access individual sections 
in the .ini files
2. wglob.ini only touches sections that hold config info which underwent 
some change during an editor session. At the moment this is achieved by 
a bisarre combination of TFile functions to remove sections and then the 
  already disdained fprintf() method to append those at the end of the 
wglob.ini file. No need to see the code -- it is ugly.

At the moment I have implemented this new set of functions (ini.h) to 
generate/replace sections in an .ini file:

BOOLEAN OpenINI(TFile *pINIFile);
void CloseINI(TFile *pINIFile);

int SearchSection(TFile *pINIFile, const char *sSectionName, int 
*nSectionStart);
int RemoveSection(TFile *pINIFile, const char *psSectionName);
BOOLEAN SectionBegin(TSectionBuf *pSection);
BOOLEAN SectionPrintF(TSectionBuf *pSection, const char *fmt, ...);
BOOLEAN SectionInsert(TFile *pINIFile, int nAtLine, TSectionBuf *pSection);

The center piece is SectionPrintF() which works as normal printf() but 
outputs in a temp buffer which can then be SectionInsert()-ed in an 
existing, and already opened, .ini file.

I began this cleanup work when I had to add a new section to wglob.ini 
to keep the current font and screen parameters for the GUI version 
(Windows and later X). Next step is to have all existing code which uses 
fprintf() be replaced with SectionPrintF().
