More verbose log message for context switches.
Use enum instead of int for fsmode.
Disable syslog-output when debugging, minor cleanups.
Don't change uid/gid when fuse context is empty.
Explicitly enable .flag_nullpath_ok and .flag_nopath.
Use setfs[ug]id instead of sete[ug]id.

Seteuid and setegid affect sibling threads under NPTL.
This makes for really nice race conditions in unsharedfs_{take,drop}_context_id.
Open newly created files as read-write.

Even though man 2 creat specifies O_CREAT|O_WRONLY|O_TRUNC as
flags for the creat call, some programs don't cope with a file that
is opened write only.

Therefore, we open it as O_RDWR.
Update in-source version to "1.1git".

Normally, this should have been done directly after tagging 1.0 :-|
