ef1ebf12d9 cmd/sharefs: handle mount -t fuse.sharefs
This should have been handled in a custom option parsing function, but that much extra complexity is unnecessary for this edge case. Honestly I do not know why libfuse does not handle this itself.

2f8ca83376 cmd/sharefs: containerise filesystem daemon
This replaces the forking daemonise libfuse function which prevents Go callbacks from calling into the runtime. This also enforces least privilege on the daemon process.

d597592e1f cmd/sharefs: rename fuse-helper to fuse-operations
This is not really just library wrapper functions, but instead implements the callbacks, so fuse-operations makes more sense.

056f5b12d4 cmd/sharefs: move translate_pathname body to macro wrapper
This is never called directly anywhere and it is simple enough to be included in the macro. This avoids passing the pointer around and dereferencing errno location, resulting in over 5% increase in throughput on the clang build. No change in the gcc build though.

da2bb546ba cmd/sharefs: remove readlink
This filesystem does not support symbolic links, so readlink is not useful, and unreachable in this case because of the check in getattr.
