Clean up and fix file listing functions.

- Merge Sys_ListFiles and Sys_ListFilteredFiles into the single
  Sys_ListFiles_r implementatation (per platform).
- Fix an off-by-one bug in Sys_ListFiles (per platform).
- Fix an off-by-one bug in FS_ListFiles.
- Made Sys_ListFiles ignore hidden and non-regular (irregular?) files on Unix.
- Limit maximum recursion depth to 8 (opposed to 32 on Unix and unlimited
  depth on Win32).
- Reduce listed files limit to 2048 from 4096.
- Implement FS_SEARCH_STRIPEXT flag instead of ugly hack in FS_File_g.
- Kill unused FS_SEARCH_NOSORT flag.
- Replace FS_SEARCHDIRS_* cruft with single FS_SEARCH_DIRSONLY flag.
- Use unsigned integer type for flags.
- Don't list more than 128 files to avoid console spam.
