Sylvain Jeaugey 5dffba1287 Rework shared memory code to use SYSCHECK macros. ...

This is to handle EINTR/EGAIN properly (issue #137), and also
make the code consistent with the rest.

Unfortunately posix_fallocate and mmap do not follow the classic
return code/errno pattern, so we need to write wrappers around those
functions.
