/** @file
INI configuration parsing library.
The INI file format is:
================
[SectionName]
EntryName=EntryValue
================
Where:
1) SectionName is an ASCII string. The valid format is [A-Za-z0-9_]+
2) EntryName is an ASCII string. The valid format is [A-Za-z0-9_]+
3) EntryValue can be:
3.1) an ASCII String. The valid format is [A-Za-z0-9_]+
3.2) a GUID. The valid format is xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx, where x is [A-Fa-f0-9]
3.3) a decimal value. The valid format is [0-9]+
3.4) a heximal value. The valid format is 0x[A-Fa-f0-9]+
4) '#' or ';' can be used as comment at anywhere.
5) TAB(0x20) or SPACE(0x9) can be used as separator.
6) LF(\n, 0xA) or CR(\r, 0xD) can be used as line break.
