List head nodes contain null 'prev' pointer, which we can (ab)use to maintain a
back reference to the tail pointer of the list.
While list additions are not _significantly_ improved, they are still sped up.

Linux lstat follows POSIX standards and dereferences a symlink pointing
to a directory if there is a trailing slash. For purposes of libalpm, we
don't want this so make a lstat wrapper that suppresses this behavior.

Don't open a stream to the logfile until necessary. This will allow us
to catch any errors in opening the logfile instead of ignorning them.

Instead of declaring the extern variable in every *.c file, include it in
the header file that makes sense. This means handle.h for the handle, and
conf.h for the pacman side config object.

I broke scriptlet logging with ad691001e2.
Readd more or less what was there before, although it still needs a lot of
work including hopefully rewriting it to a new event subsystem and having
it log to a seperate file.

Hopefully these new autoconf macros, with a little magic, will allow us to
compile with any compiler and still choose the options we have available
to us.
Tested locally with gcc 4.2.2 and gcc 3.4.6; the latter doesn't support two
of the items we previously had hardcoded in our CFLAGS.

%d was used, which worked for Linux and FreeBSD. Not so for Darwin. The
warning was probably spat out when compiling on x68_64 as well, but no
developers use this architecture as their primary one.

Package dup needs to copy all members. Nathan had his implementation, but
I generalized it to this new alpm_list function (and will use it in the
next commit).

These macros take the place of the common 4 or 5 line blocks of code we had
in most places that called malloc or calloc. This should reduce some code
duplication and make memory allocation more standard in libalpm.
Highlights:
* Note that the MALLOC macro actually uses calloc, this is just for safety
so that memory is initialized to 0. This can be easily changed in one
place.
* One malloc call was completely eliminated- it made more sense to do it
on the stack.
* The use of RET_ERR in public functions (mainly the alpm_*_new functions)
was standardized, this makes sense so pm_errno is set.

We had a lot of unnecessary overstatements of libraries to include on
linking, and autoconf/automake takes care of this for us. This also helps

The old code used memcmp, which is not good for comparing strings:
"pkgname"'\0''\0' should be equal to "pkgname"'\0''a' for example.

The code didn't match the following comment :
"A depends on B through n depends <=> A listed in B's requiredby n times"
It stopped at n=1 with a break.
I was surprised to see this case happens in real, that's how I noticed the
bug: wine depends on both freeglut and glut, while freeglut provides glut.
So when installing wine, the update_depends function listed wine twice in
freeglut's requiredby. But the compute_requiredby function (used when
installing freeglut, and used by testdb) listed wine only once in
freeglut's requiredby. That made testdb unhappy.

Commit 4853a4aad9 used the tmpdir variable
for checking the existence of /bin/sh, without resetting it.
This caused /bin/sh to be deleted during the cleanup part, as soon as a scriptlet
other than pre_upgrade or pre_install was executed.
For example, on the first post_upgrade during a -Su.
I introduced two variables : clean_tmpdir and restore_cwd, for deciding what should
be done in the cleanup part.

This code assumed that DBPath was under RootDir, while this is not necessarily the case :
pacman doesn't enforce anymore than DBPath is under RootDir.
So now, all scriptlets will be put somewhere in RootDir/tmp/, so that when it chroots in RootDir,
the scriptlets are still available inside the chroot.
This also removes the need of normalizing both dbpath and rootdir, in order to do computation on the paths.

We had way too much going on with the Doxygen manpage generation. Clean it
up quite a bit by removing directory manpages, using relative paths, not

Change the default visibility of libalpm functions to internal instead of
hidden- this allows for slightly better optimization because it tells GCC
that the function can never be called outside of the current module (see
http://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html).
Also added some attributes to the pacman print functions so that they check
the format strings being passed to them.

The md5 routines are one of the chokepoints of libalpm (main chokepoint being

Packages and DBs now support using the UNIX epoch (seconds since Jan 1, 1970)
for use in builddate and installdate. This will only affect newly built
packages. Old existing packages with the text format are still supported, but
this is deprecated.
In the case of removal of text time support, this code will fail gracefully,
returning the start of the epoch for broken packages.

In most cases, we want to fully scan a package when we load it, which serves
as a integrity verification check. However, there are times when it is only
desired to read the metadata and nothing else, so allow the caller of pkg_load
to choose the behavior they need.
This pays big dividends in speeding up pacman cache cleaning functionality.
