fast-import: Fail if a non-existant commit is used for merge
fast-import: Avoid infinite loop after reset
[sp: Minor evil merge to deal with type_names array moving
to be private in 'master'.]
Johannes Sixt noticed during one of his own imports that fast-import
did not fail if a non-existant commit is referenced by SHA-1 value
as an argument to the 'merge' command. This allowed the user to
unknowingly create commits that would fail in fsck, as the commit
contents would not be completely reachable.
A side effect of this bug was that a frontend process could mark
any SHA-1 object (blob, tree, tag) as a parent of a merge commit.
This should also fail in fsck, as the commit is not a valid commit.
We now use the same rule as the 'from' command. If a commit is
referenced in the 'merge' command by hex formatted SHA-1 then the
SHA-1 must be a commit or a tag that can be peeled back to a commit,
the commit must already exist, and must be readable by the core Git
infrastructure code. This requirement means that the commit must
have existed prior to fast-import starting, or the commit must have
been flushed out by a prior 'checkpoint' command.

Johannes Sixt noticed that a 'reset' command applied to a branch that
is already active in the branch LRU cache can cause fast-import to
relink the same branch into the LRU cache twice. This will cause
the LRU cache to contain a cycle, making unload_one_branch run in an
infinite loop as it tries to select the oldest branch for eviction.
I have trivially fixed the problem by adding an active bit to
each branch object; this bit indicates if the branch is already
in the LRU and allows us to avoid trying to add it a second time.
Converting the pack_id field into a bitfield makes this change take
up no additional memory.

git-fsck always exited with status 0, which was a bit sloppy.
This makes it exit with a non-zero status when errors are
found. The error code is an OR'ed result of:
1 if corrupted objects are found.
2 if objects that are ought to be reachable are missing or corrupt.
For example, it would exit with 1 in a repository with an
unreachable corrupt object. If a tree object of the HEAD commit
is corrupt, you would get 3.

We did not detect broken loose object files, either when
underlying inflate() signalled the breakage, nor inflate()
finished and we had garbage trailing at the end. We do better
now.
We also make unpack_sha1_file() a static function to
sha1_file.c, since it is not used by anybody outside.
Signed-off-by: Junio C Hamano <junkio@cox.net>
When "git fsck" without --full found a loose object missing
because it was broken, it mistakenly thought it was not parsed
because we found it in one of the packs. Back when this code
was written, we did not have a way to explicitly check if we
have the object in pack, but we do now.

The existing --attach option did not create a true "attachment"

have been with Content-Disposition: attachment.

The earlier commit to read from stdin was full of problems, and
this corrects them.
- The mode bits should have been set to satisify S_ISREG(); we
forgot to the S_IFREG bits and hardcoded 0644;
- We did not give escape hatch to name a path whose name is
really "-". Allow users to say "./-" for that;
- Use of xread() was not prepared to see short read (e.g. reading
from tty) nor handing read errors.

Some file systems that can host git repositories and their working copies
do not support symbolic links. But then if the repository contains a symbolic
link, it is impossible to check out the working copy.
This patch enables partial support of symbolic links so that it is possible
to check out a working copy on such a file system. A new flag
core.symlinks (which is true by default) can be set to false to indicate
that the filesystem does not support symbolic links. In this case, symbolic
links that exist in the trees are checked out as small plain files, and
checking in modifications of these files preserve the symlink property in
the database (as long as an entry exists in the index).
Of course, this does not magically make symbolic links work on such defective
file systems; hence, this solution does not help if the working copy relies
on that an entry is a real symbolic link.
