[PATCH] v2. replace ALL svn_wc_entry() in libsvn_client/patch.c

Hi!
It's better to do the whole file at once, I think.

make check was clean except for:
external_tests.py 16
switch_tests.py 18, 21

They also fail on trunk for me.

[[[
Replaced svn_wc_entry() with svn_wc__get_entry_versioned(). Catch
SVN_ERR_ENTRY_NOT_FOUND since it is not expected.

* subversion/libsvn_client/patch.c
  (merge_file_changed, merge_file_added, merge_file_deleted,
  merge_dir_added, init_patch_target): Replaced svn_wc_entry(). Used
    absolute paths.
]]]

Mvh
