8cffe412ea Include config.h before all other headers. 
The defines in config.h may affect OS and FUSE API and ABI, so make sure
to include it before everything else.

75becf3606 Fix binary compatibility between fuse and others. 
CFLAGS from fuse.pc may affect ABI, e.g. enable 64-bit inode numbers on
Mac OS X 10.5. Propagate FUSE CFLAGS to all other components to ensure
binary compatibility.

57912599d8 Do not treat device opening error as FS error. 
This makes more sense, e.g. when the user mistyped the device name or

4e6606bb5f Fix cluster bitmap traversal on big endian machines. 
We define bitmap_t to unsigned char on big endian systems to avoid byte
order conversions. But bitwise complement causes integer promotion and
makes the condition always false. Truncate the result after complementing
zero.

75f28b558a Add support for timezone offsets. 
Timestamps are stored in local time. exFAT includes timezone offset
fields to allow timestamps to remain correct when mounted under a
different timezone. The timezone offset is now used to calculate the
correct timestamp on read, and set on write.

21fab6b208 Fix searching for free slots in the root directory. 
When we need to place n entries and slot at position x is occupied, we
should check x+1 instead of jumping to x+n. Otherwise we may end up
putting new entries beyond a 0x00 entry, which Windows 10 interprets as
an end-of-directory mark and does not look farther.
