safehasattr: pass attribute name as string instead of bytes

This is a step toward replacing `util.safehasattr` usage with plain `hasattr`.

These change are done one by one as they tend to have a small odd to trigger
puzzling breackage.

This test file test the various templates related to obsmarkers.

Test metadata encoding (issue5754)
==================================

  $ hg init $TESTTMP/metadata-encoding

  $ mkcommit ROOT
  $ ( HGENCODING=latin-1 HGUSER="`cat test1`" mkcommit A0 )
  $ echo 42 >> A0
  $ HGENCODING=latin-1 hg amend -m "A1" --note "`cat test2`"
  $ HGENCODING=latin-1 hg amend -m "A2" \

  $ mkcommit B0
  $ HGENCODING=latin-1 hg debugobsolete -u "`cat test2`" "`getid 'desc(B0)'`"
  1 new obsolescence markers
  obsoleted 1 changesets

metadata should be stored in UTF-8, and debugobsolete doesn't decode it to
local encoding since the command is supposed to show unmodified content:

  $ HGENCODING=latin-1 hg debugobsolete

metadata should be converted back to local encoding when displaying:
