This patch checks that a '[PRnnnn]' and '(PRnnnn)' also appears as PR in the
changelog part of the commit message.  And it does likewise for 'PR comp/nnnn'
except that then also the component name is checked.  (Note that the reverse
is permitted, i.e. PR(s) only appearing in the changelog.)
To avoid false positives, PR numbers in the subject line are ignored,
if 'revert' appears.
Additionally, reject commits with a nonempty second line.

Only '(' and ':' currently terminate file lists in ChangeLog entries
in the ChangeLog parser.  This rules out such legitimate entries as:

* filename <CASE>:

This patch extends the ChangeLog parser to recognize these forms.

Renamed files are listed in the following format:

M	gcc/ada/Makefile.rtl
M	gcc/ada/impunit.adb
R097	gcc/ada/libgnat/s-atopar.adb	gcc/ada/libgnat/s-aoinar.adb
R095	gcc/ada/libgnat/s-atopar.ads	gcc/ada/libgnat/s-aoinar.ads
A	gcc/ada/libgnat/s-aomoar.adb
A	gcc/ada/libgnat/s-aomoar.ads

So 'R' is followed by a percentage number.

So far, we expect from a commit that renames a file to contain a
changelog entry only for the new name. For example, after the following
commit:

   $ git move foo bar
   $ git commit

We expect the following changelog:

   * bar: Renamed from foo.

Git does not keep track of renamings, only file deletions and additions.
The display of patches then uses heuristics (with config-dependent
parameters) to try to match deleted and added files in the same commit.
It is thus brittle to rely on this information.

This commit modifies changelog processing so that renames are considered
as a deletion of a file plus an addition of another file. The following
changelog is now expected for the above example:

   * foo: Move...
   * bar: Here.

contrib/

	* gcc-changelog/git_email.py (GitEmail.__init__): Interpret file
	renamings as a file deletion plus a file addition.
	* gcc-changelog/git_repository.py (parse_git_revisions):
	Likewise.
	* gcc-changelog/test_email.py: New testcase.
	* gcc-changelog/test_patches.txt: New testcase.

This extends the ChangeLog entries parsing machinery to handle entries
that cover multiple files spanning over multiple lines. For instance:

    * first_file_patched.c, second_file_patched.c, third_file_patched.c,
    fourth_file_patched.c: Do things.

contrib/

	* gcc-changelog/git_commit.py (ChangeLogEntry): Handle entries
	with multi-line file lists.
	* gcc-changelog/test_email.py: New testcase.
	* gcc-changelog/test_patches.txt: Likewise.
