setup_revisions(): take pathspec from command line and --stdin correctly
When the command line has "--" disambiguator, we take the remainder of

we need to append to the existing prune_data and end up attempting to
realloc(3) it. That would not work.

As v1.6.0-rc2~42 (Allow "non-option" revision options in
parse_option-enabled commands, 2008-07-31) explains, options handled
by setup_revisions fall into two categories:
1. global options like --topo-order handled by parse_revision_opt,
which can take detached arguments and can be parsed in advance;
2. pseudo-options that must be parsed in order with their revision
counterparts, like --not and --all.
The global options are taken care of by handle_revision_opt; the
pseudo-options are currently in a deeply indented portion of
setup_revisions. Give them their own function for easier reading.
The only goal is to make setup_revisions easier to read straight
through. No functional change intended.

We already have --show-notes, but it has a few shortcomings:
1. Using --show-notes=<ref> implies that we should also
show the default notes. Which means you also need to
use --no-standard-notes if you want to suppress them.
2. It is negated by --no-notes, which doesn't match.
3. It's too long to type. :)
This patch introduces --notes, which behaves exactly like
--show-notes, except that using "--notes=<ref>" does not
imply showing the default notes.

revision.c: introduce --min-parents and --max-parents options
t6009: use test_commit() from test-lib.sh
Introduce --min-parents and --max-parents options which limit the
revisions to those commits which have at least (or at most) that many
commits, where negative arguments for --max-parents= denote infinity
(i.e. no upper limit).
In particular:
--max-parents=1 is the same as --no-merges;
--min-parents=2 is the same as --merges;
--max-parents=0 shows only roots; and
--min-parents=3 shows only octopus merges
Using --min-parents=n and --max-parents=m with n>m gives you what you ask
for (i.e. nothing) for obvious reasons, just like when you give --merges
(show only merge commits) and --no-merges (show only non-merge commits) at
the same time.
Also, introduce --no-min-parents and --no-max-parents to do the obvious
thing for convenience.
We compute the number of parents only when we limit by that, so there
is no performance impact when there are no limiters.

The existing "--cherry-pick" does not work with unsymmetric ranges
(A..B) for obvious reasons.
Introduce "--left-only" and "--right-only" which limit the output to
commits on the respective sides of a symmetric range (i.e. only "<"
resp. ">" commits as per "--left-right").
This is especially useful for things like
git log --cherry-pick --right-only @{u}...
which is much more flexible (and descriptive) than
git cherry @{u} | sed -ne 's/^+ //p'

git log --cherry-pick @{u}...

The reflog-walking mechanism is based on the regular
revision traversal. We just rewrite the parents of each
commit in fake_reflog_parent to point to the commit in the
next reflog entry instead of the real parents.
However, the regular revision traversal tries not to show
the same commit twice, and so sets the SHOWN flag on each
commit it shows. In a reflog, however, we may want to see
the same commit more than once if it appears in the reflog
multiple times (which easily happens, for example, if you do
a reset to a prior state).
The fake_reflog_parent function takes care of this by
clearing flags, including SHOWN. Unfortunately, it does so
at the very end of the function, and it is possible to
return early from the function if there is no fake parent to
set up (e.g., because we are at the very first reflog entry
on the branch). In such a case the flag is not cleared, and
the entry is skipped by the revision traversal machinery as
already shown.
You can see this by walking the log of a ref which is set to
its very first commit more than once (the test below shows
such a situation). In this case the reflog walk will fail to
show the entry for the initial creation of the ref.
We don't want to simply move the flag-clearing to the top of
the function; we want to make sure flags set during the
fake-parent installation are also cleared. Instead, let's
hoist the flag-clearing out of the fake_reflog_parent
function entirely. It's not really about fake parents
anyway, and the only caller is the get_revision machinery.

Add a --count option that, instead of actually listing the commits,

This is mostly geared towards script use, and to this end it acts
specially when used with --left-right: it outputs the left and right

or small inline script over to achieve the same. (Without
--left-right, a simple |wc -l does the job.)

When using --ancestry-path together with history simplification (typically
triggered by path limiting), history simplification would get in the way of
--ancestry-path by prematurely removing the parent links between commits on
which the ancestry path calculations are made.
This patch disables this history simplification when --ancestry-path is
enabled. This is similar to what e.g. --full-history already does.
The patch also includes a simple testcase verifying that --ancestry-path
works together with path limiting.

To show the last two commits with one command, one might try
1) git show -s master~2..
2) git show -s ^master~2 master
3) git show -s master^ master
4) git show -s -2 master
Choice (3) works because both commits are listed on the command line.
Choices (1) and (2) have worked ever since v1.6.4-rc~3 (Make 'git
show' more useful, 2009-07-13) disabled --no-walk in this case because
there is no other useful meaning for them to have. Unfortunately, (4)
does not work: it outputs only one commit, because --no-walk stays on.
So disable --no-walk in this case so ‘git show’ and future ‘git
cherry-pick’ can behave as expected.
As a side effect, this unfortunately changes the meaning of
‘git log --oneline --decorate --no-walk -5 --all’: instead of listing
five refs, after this patch that command would list the five most
recent commits.
