//	Stolen from mDNS.c's mDNS_snprintf/mDNS_vsnprintf with the following changes:
//
//	Changed names to avoid name collisions with the mDNS versions.
//	Changed types to standard C types since mDNSEmbeddedAPI.h may not be available.
//	Conditionalized mDNS stuff so it can be used with or with mDNSEmbeddedAPI.h.
//	Added 64-bit support for %d (%lld), %i (%lli), %u (%llu), %o (%llo), %x (%llx), and %b (%llb).
//	Added %@   - Cocoa/CoreFoundation object. Param is the object. Strings are used directly. Others use CFCopyDescription.
//	Added %.8a - FIbre Channel address. Arg=ptr to address.
//	Added %##a - IPv4 (if AF_INET defined) or IPv6 (if AF_INET6 defined) sockaddr. Arg=ptr to sockaddr.
//	Added %b   - Binary representation of integer (e.g. 01101011). Modifiers and arg=the same as %d, %x, etc.
//	Added %C   - Mac-style FourCharCode (e.g. 'APPL'). Arg=32-bit value to print as a Mac-style FourCharCode.
//	Added %H   - Hex Dump (e.g. "\x6b\xa7" -> "6B A7"). 1st arg=ptr, 2nd arg=size, 3rd arg=max size.
//	Added %#H  - Hex Dump & ASCII (e.g. "\x41\x62" -> "6B A7 'Ab'"). 1st arg=ptr, 2nd arg=size, 3rd arg=max size.
//	Added %m   - Error Message (e.g. 0 -> "kNoErr"). Modifiers and error code args are the same as %d, %x, etc.
//	Added %S   - UTF-16 string. Host order if no BOM. Precision is UTF-16 char count. BOM counts in any precision. Arg=ptr.
//	Added %#S  - Big Endian UTF-16 string (unless BOM overrides). Otherwise the same as %S.
//	Added %##S - Little Endian UTF-16 string (unless BOM overrides). Otherwise the same as %S.
//	Added %U   - Universally Unique Identifier (UUID) (e.g. 6ba7b810-9dad-11d1-80b4-00c04fd430c8). Arg=ptr to 16-byte UUID.
