Implement fs::file::get_id()

Browse source 
File descripor ID with 2 provided ways to compare between them:
1. is_mirror_of():
 Test if identical:
  For example: when LHS writes one byte to a file at X offset, RHS file be able to read that exact byte at X offset)

2. is_coherent_with():
 Test if both files point to the same file:
  For example: if a file descriptor pointing to the complete file exists and is being truncated to 0 bytes from non-
  -zero size state: this has to affect both RHS and LHS files.
