fmtutil and tlmgr improvements

fmtutil.pl
- if run as mktexfmt and TEXMFSYSVAR is writable, use
  it instead of TEXMFVAR (actual code in TLUtils.pm).
- add --dry-run | -n option
  it is not guaranteed to be 100% dry-run, though
- add --status-file=FILE where the status of each
  format creating is written to
- warn on running fmtutil in user mode the first time
  (similar to updmap)
- warn on shadowing formats
- documentation fixes

tlmgr.pl
- use fmtutil --status-file and report back failed
  format rebuilds
- regeneration all formats now only exists existing
  formats (use --refresh with fmtutil)
- report when commands are logged to the respective
  log file
- documentation fixes

TLUtils.pm
- update setup_sys_user_mode for the fmtutil/mktexfmt
  changes mentioned above
- documentation fixes
