The --changes-block-size handling was intended to help when
a user has a limited "maxscanrows" (see "p4 group"). It used
"p4 changes -m $maxchanges" to limit the number of results.
Unfortunately, it turns out that the "maxscanrows" and "maxresults"
limits are actually applied *before* the "-m maxchanges" parameter
is considered (experimentally).
Fix the block-size handling so that it gets blocks of changes
limited by revision number ($Start..$Start+$N, etc). This limits
the number of results early enough that both sets of tests pass.
Note that many other Perforce operations can fail for the same
reason (p4 print, p4 files, etc) and it's probably not possible
to workaround this. In the real world, this is probably not
usually a problem.

Since 45e8a74 (has_sha1_file: re-check pack directory before
giving up, 2013-08-30), we spend extra effort for
has_sha1_file to give the right answer when somebody else is
repacking. Usually this effort does not matter, because
after finding that the object does not exist, the next step
is usually to die().
However, some code paths make a large number of
has_sha1_file checks which are _not_ expected to return 1.
The collision test in index-pack.c is such a case. On a
local system, this can cause a performance slowdown of
around 5%. But on a system with high-latency system calls
(like NFS), it can be much worse.
This patch introduces a "quick" flag to has_sha1_file which
callers can use when they would prefer high performance at
the cost of false negatives during repacks. There may be
other code paths that can use this, but the index-pack one
is the most obviously critical, so we'll start with
switching that one.

The diff and submodule shortlog appended to the commit message template
by 'git commit --verbose' are not stripped when the commit message
contains an indented scissors line.
When cleaning up a commit message with 'git commit --verbose' or
'--cleanup=scissors' the code is careful and triggers only on a pure
scissors line, i.e. a line containing nothing but a comment character, a
space, and the scissors cut. This is good, because people can embed
scissors lines in the commit message while using 'git commit --verbose',
and the text they write after their indented scissors line doesn't get
deleted.
While doing so, however, the cleanup function only looks at the first
line matching the scissors pattern and if it doesn't start at the
beginning of the line, then the function just returns without performing
any cleanup. This is wrong, because a "real" scissors line added by
'git commit --verbose' might follow, and in that case the diff and
submodule shortlog get included in the commit message.
Fix this by changing the scissors pattern to match only at the beginning
of the line, yet be careful to catch scissors on the first line as well.

Since 7b3b7e3 (am --abort: keep unrelated commits since the last failure
and warn, 2010-12-21), git-am would refuse to rewind HEAD if commits
were made since the last git-am failure. This check was implemented in
safe_to_abort(), which checked to see if HEAD's hash matched the
abort-safety file.
However, this check was skipped if the abort-safety file was empty,
which can happen if git-am failed while on an unborn branch. As such, if
any commits were made since then, they would be discarded. Fix this by
carrying on the abort safety check even if the abort-safety file is
empty.

As such, any applied commits will remain even after a git am --abort.

Even when a merge conflict occurs with am --3way, the index will be

changes to the index will not be reverted with a

aware of how the current index differs from HEAD or ORIG_HEAD.
To fix this, we first reset any conflicting entries in the index. The
resulting index will contain the results of successfully merged files
introduced by the failed merge. We write this index to a tree, and then
use git read-tree to fast-forward this "index tree" back to ORIG_HEAD,
thus undoing all the changes from the failed merge.

NULL_SHA1 is used to indicate an "invalid object name" throughout our
code (and the code of other git implementations), so it is vastly more
likely that an on-disk reference was set to this value due to a
software bug than that NULL_SHA1 is the legitimate SHA-1 of an actual
object. Therefore, if a loose reference has the value NULL_SHA1,
consider it to be broken.

Before this change, t7063.17 fails. The actual action though happens at
t7063.16 where the entry "two" is added back to index after being
removed in the .13. Here we expect a directory invalidate at .16 and
none at .17 where untracked cache is refreshed. But things do not go as
expected when GIT_TEST_SPLIT_INDEX is set.
The different behavior that happens at .16 when split index is used: the
entry "two", when deleted at .13, is simply marked "deleted". When .16
executes, the entry resurfaces from the version in base index. This
happens in merge_base_index() where add_index_entry() is called to add
"two" back from the base index.
This is where the bug comes from. The add_index_entry() is called with
ADD_CACHE_KEEP_CACHE_TREE flag because this version of "two" is not new,
it does not break either cache-tree or untracked cache. The code should
check this flag and not invalidate untracked cache. This causes a second
invalidation violates test expectation. The fix is obvious.

Change the --changes-block-size git-p4 test to use an account with
limited "maxresults" and "maxscanrows" values.
These conditions are applied in the server *before* the "-m maxchanges"
parameter to "p4 changes" is applied, and so the strategy that git-p4
uses for limiting the number of changes does not work. As a result,
the tests all fail.
Note that "maxscanrows" is set quite high, as it appears to not only
limit results from "p4 changes", but *also* limits results from
"p4 print". Files that have more than "maxscanrows" changes seem
(experimentally) to be impossible to print. There's no good way to
work around this.

The last argument of reencode_string_len() is an 'int *' which is
assigned the length of the converted string. When NO_ICONV is defined,
however, reencode_string_len() is stubbed out by the macro:
#define reencode_string_len(a,b,c,d,e) NULL
which never assigns a value to the final argument. When called like
this:
int n;
char *s = reencode_string_len(..., &n);
if (s)
do_something(s, n);
