This will become an umbrella program that absorbs most [1] t/helper
programs in. By having a single executable binary we reduce disk usage
(libgit.a is replicated by every t/helper program) and shorten link
time a bit.
Running "make --jobs=1; du -sh t/helper" with ccache fully populated,
it takes 27 seconds and 277MB at the beginning of this series, 17
seconds and 42MB at the end.
[1] There are a couple programs that will not become part of
test-tool: test-line-buffer and test-svn-fe have extra
dependencies and test-fake-ssh's program name has to be a single
word for some ssh tests.

Clean-up to various pieces of Perl code we have.
* ab/perl-fixes:
perl Git::LoadCPAN: emit better errors under NO_PERL_CPAN_FALLBACKS
Makefile: add NO_PERL_CPAN_FALLBACKS knob
perl: move the perl/Git/FromCPAN tree to perl/FromCPAN
perl: generalize the Git::LoadCPAN facility
perl: move CPAN loader wrappers to another namespace
perl: update our copy of Mail::Address
perl: update our ancient copy of Error.pm
git-send-email: unconditionally use Net::{SMTP,Domain}
Git.pm: hard-depend on the File::{Temp,Spec} modules
gitweb: hard-depend on the Digest::MD5 5.8 module
Git.pm: add the "use warnings" pragma
Git.pm: remove redundant "use strict" from sub-package
perl: *.pm files should not have the executable bit
Before my 20d2a30f8f ("Makefile: replace perl/Makefile.PL with simple
make rules", 2017-12-10) on an OS package that removed the
private-Error.pm copy we carried around manually removing the OS's
Error.pm would yield:
$ git add -p
Can't locate Error.pm in @INC (you may need to install the Error module) [...]
Now, before this change we'll instead emit this more cryptic error:
$ git add -p
BUG: '/usr/share/perl5/Git/FromCPAN' should be a directory! at /usr/share/perl5/Git/Error.pm line 36.
This is a confusing error. Now if the new NO_PERL_CPAN_FALLBACKS
option is specified and we can't find the module we'll instead emit:
$ /tmp/git/bin/git add -p
BUG: The 'Error' module is not here, but NO_PERL_CPAN_FALLBACKS was set!
[...]
Where [...] is the lengthy explanation seen in the change below, which
explains what the potential breakage is, and how to fix it.
The reason for checking @@NO_PERL_CPAN_FALLBACKS@@] against the empty
string in Perl is as opposed to checking for a boolean value is that
that's (as far as I can tell) make's idea of a string that's set, and
e.g. NO_PERL_CPAN_FALLBACKS=0 is enough to set NO_PERL_CPAN_FALLBACKS.

We include some perl modules which are not part of the core perl
install, as a convenience. This allows us to rely on those modules in
our perl-based tools and scripts without requiring users to install the
modules from CPAN or their operating system packages.
Users whose operating system provides these modules and packagers of Git
often don't want to ship or use these bundled modules. Allow these
users to set NO_PERL_CPAN_FALLBACKS to avoid installing the bundled
modules.

Move the CPAN modules that have lived under perl/Git/FromCPAN since my
20d2a30f8f ("Makefile: replace perl/Makefile.PL with simple make
rules", 2017-12-10) to perl/FromCPAN.
A subsequent change will teach the Makefile to only install these
copies of CPAN modules if a flag that distro packagers would like to
set isn't set. Due to how the wildcard globbing is being done it's
much easier to accomplish that if they're moved to their own
directory.

Support for generating an rpm was dropped in ab214331cf ("Makefile: stop
pretending to support rpmbuild", 2016-04-04). We don't generate any
*.spec files so there is no need to clean them up.

Push the submodule version of collision-detecting SHA-1 hash
implementation a bit harder on builders.
* ab/sha1dc-build:
sha1dc_git.h: re-arrange an ifdef chain for a subsequent change
Makefile: under "make dist", include the sha1collisiondetection submodule
Makefile: don't error out under DC_SHA1_EXTERNAL if DC_SHA1_SUBMODULE=auto
Since commit 20d2a30f8f (Makefile: replace perl/Makefile.PL with
simple make rules, 2017-12-10), the Git(3pm) man page is only
generated as an indirect dependency of the 'install-doc' and
'install-man' Makefile targets. Consequently, if someone runs 'make
man && sudo make install-man' (or their 'doc' counterparts), then
Git(3pm) will be generated as root, and the resulting root-owned files
and directories will in turn cause the next user-run 'make clean' to
fail. This was not an issue in the past, because Git(3pm) was
generated when 'make all' descended into 'perl/', which is usually not
run as root.
List Git(3pm) as a dependency of the 'doc' and 'man' Makefile targets,
too, so it gets generated by targets that are usually built as
ordinary users.
While at it, add 'install-man-perl' to the list of .PHONY targets.

Retire mru API as it does not give enough abstraction over
underlying list API to be worth it.
* gs/retire-mru:
mru: Replace mru.[ch] with list.h implementation
In preparation for implementing narrow/partial clone, the machinery
for checking object connectivity used by gc and fsck has been
taught that a missing object is OK when it is referenced by a
packfile specially marked as coming from trusted repository that
promises to make them available on-demand and lazily.
* jh/fsck-promisors:
gc: do not repack promisor packfiles
rev-list: support termination at promisor objects
sha1_file: support lazily fetching missing objects
introduce fetch-object: fetch one promisor object
index-pack: refactor writing of .keep files
fsck: support promisor objects as CLI argument
fsck: support referenced promisor objects
fsck: support refs pointing to promisor objects
fsck: introduce partialclone extension
extension.partialclone: introduce partial clone extension
The build procedure for perl/ part has been greatly simplified by
weaning ourselves off of MakeMaker.
* ab/simplify-perl-makefile:
perl: treat PERLLIB_EXTRA as an extra path again
perl: avoid *.pmc and fix Error.pm further
Makefile: replace perl/Makefile.PL with simple make rules
Sparse has, for a long time, been issuing the following warning against
the pack-revindex.c file:
SP pack-revindex.c
pack-revindex.c:64:23: warning: memset with byte count of 262144
This results from a unconditional check, with a hard-coded limit, which
is really only appropriate for the kernel source code. (The check is for
a 'large' byte count in a call to memcpy(), memset(), copy_from_user()
and copy_to_user() functions).
A recent release of sparse (v0.5.1) has introduced some options to allow
this check to be turned off (-Wno-memcpy-max-count) or to specify the
actual limit used (-fmemcpy-max-count=COUNT), rather than a hard-coded
limit of 100000.
In order to suppress the warning, add a target for pack-revindex.sp that
adds the '-Wno-memcpy-max-count' option to the SPARSE_FLAGS variable.

Replace the custom calls to mru.[ch] with calls to list.h. This patch is
the final step in removing the mru API completely and inlining the logic.
This patch leads to significant code reduction and the mru API hence, is
not a useful abstraction anymore.
