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.

Rework SYSCHECK macros to better handle retries.
...
SYSCHECKVAL was not retrying when a retry was needed. Since not all
calls are inside a loop, that means we could silently miss an
EINTR/EAGAIN return code.
Also rework the socket connection code and improve error reporting.
