faf2d0b537 chunker: fix invalid use of types 
With the argument specified as unsigned char *, Cython emits
code in the Python wrapper to convert string-like objects to
unsigned char* (essentially PyBytes_AS_STRING).

Because the len(data) call is performed on a cdef'd string-ish type,
Cython emits a strlen() call, on the result of PyBytes_AS_STRING.

This is not correct, since embedded null bytes are entirely possible.

Incidentally, the code generated by Cython was also not correct,
since the Clang Static Analyzer found a path of execution where
passing arguments in a weird way from Python resulted in strlen(NULL).

Formulated like this, Cython emits essentially:

c_buzhash(
 PyBytes_AS_STRING(data),
 PyObject_Length(data),
 ...
)

which is correct.

c791921951 fuse: instrument caches 
note: signal processing can be arbitrarily delayed;
Python processes signals as soon as the code returns into the interpreter
loop, which doesn't happen unless libfuse returns control, i.e.
some request has been sent to the file system.

0b00c14c27 don't write to disk with --stdout, fixes #2645 
if we always give stdout to extract_item(), it gets into the stdout-
processing branch which only emits data from items that have chunks
and does nothing for items which don't.

78cbf695c4 cache sync: suppress GCC C90/C99 int literal warning 
warning: this decimal constant is unsigned only in ISO C90

Raised by GCC 4.9.2 on PowerPC.

The warning is bogus here due to the immediate explicit cast; newer
versions don't emit it.
