Fixed a complie error when FF_FS_LOCK != 0. (appeared at R0.15)

Fixed a potential issue when work FatFs concurrency with FF_FS_REENTRANT, FF_VOLUMES >= 2 and FF_FS_LOCK > 0.

Made f_setlabel accept a volume label with Unix style volume ID when FF_STR_VOLUME_ID == 2.

Made FatFs update PercInUse field in exFAT VBR. (A preceding f_getfree is needed for the accuracy)

<p>FatFs is a generic FAT/exFAT filesystem module for small embedded systems. The FatFs module is written in compliance with ANSI C (C89) and completely separated from the disk I/O layer. Therefore it is independent of the platform. It can be incorporated into small microcontrollers with limited resource, such as 8051, PIC, AVR, ARM, Z80, RX and etc. Also Petit FatFs module for tiny microcontrollers is available <a href="http://elm-chan.org/fsw/ff/00index_p.html">here</a>.</p>

<p>Since FatFs module is the <em>Filesystem Layer</em> independent of platforms and storage media, it is completely separated from the physical devices, such as memory card, harddisk and any type of storage device. The storage device control module is <em>not any part of FatFs module</em> and it needs to be provided by implementer. FatFs controls the storage devices via a simple media access interface shown below. Also sample implementations for some platforms are available in the downloads. A function checker for storage device control module is available <a href="res/app4.c">here</a>.</p>
