Improved support for fstat, readlink, and error returns #18

Closed mplegendre closed 6 years ago

mplegendre commented 6 years ago

One major feature:

The session workflow branch now supports running multiple slurm jobs through a single spindle session.

Several fixes:

Hide spindle caching effects when processes readlink of /proc/pid/exe via the libc call
Several types of open/stat/exec calls to libraries/executables could return wrong errno values under spindle. Some difficult-to-fix cases remain related to ENOTDIR error codes.
Fix fstat results when pointed at FDs to relocated libraries. You used to get stat results of the cached file, now you get stat results of the original file.
