We didn't do due diligence before and ensure prior pm_errno values
weren't influencing what happened in further ALPM calls. I observed one
case of early setup code setting pm_errno to PM_ERR_WRONG_ARGS and that
flag persisting the entire time we were calling library code.
Add a new CHECK_HANDLE() macro that does two things: 1) ensures the
handle variable passed to it is non-NULL and 2) clears any existing
pm_errno flag set on the handle. This macro can replace many places we
used the ASSERT(handle != NULL, ...) pattern before.
Several other other places only need a simple 'set to zero' of the
pm_errno field.

This kills a lot more global handle business off. sync.c still requires
the handle declaration for one reference that can't be changed yet; it
will be removed in a future patch which isolates all of the necesary API

The usefulness of this is rather limited due to it not being compiled
into production builds. When you do choose to see the output, it is
often overwhelming and not helpful. The best bet is to use a debugger
and/or well-placed fprintf() statements.

This addresses FS#24292. If one does the bad thing of not checking
pm_errno after calling set_dbpath(), you may not realize the
initialization process went wrong and calling trans_init() resulted in a
segfault. If we don't have a lockfile path, bail out and have
trans_init() fail.
Also remove a ALPM_LOG_FUNC call that was causing pm_errno to return "no
handle"; this was due to a log call in the handle setup (whereby the log
attempts to use a callback attached to the handle).

The addition of the DB version check introduces a lag time between the
lockfile creation and the transaction initialization. In cases where the
local DB is large enough and/or the user's disk is slow enough, this
time is significant enough that its possible for a user to send a SIGINT
and leave behind a db.lck file.

Ensure we have a local DB version that is up to par with what we expect

According to FOPEN(3), using fclose on an fdopen'd file stream also
closes the underlying file descriptor. This happened in _alpm_lckmk
(util.c), which meant that when alpm_trans_release closed it again, the
log file (which reused the original file descriptor) was closed instead.

POSIX does not require PATH_MAX be defined when there is not actual
limit to its value. This affects HURD based systems. Work around
this by defining PATH_MAX to 4096 (as on Linux) when this is not
defined.
Also, clean up inclusions of limits.h and remove autoconf check for
this header as we do not use macro shields for its inclusion anyway.

If we have a corrupted database, a package can come through without an arch,
causing the code to blow up when making strcmp() calls. It might even be
possible with perfectly valid database entries lacking an 'arch =' line.
This behavior was seen as at least one of the problems in FS#21668.
Ensure pkgarch is not null before doing anything further.

[Allan: BIG rebase]

From the fgets manpage:
fgets() reads in at most one less than size characters from stream and
stores them into the buffer pointed to by s. Reading stops after an EOF
or a newline. If a newline is read, it is stored into the buffer. A
'\0' is stored after the last character in the buffer.
This means there is no need at all to do 'size - 1' math. Remove all of that
and just use sizeof() for simplicity on the buffer we plan on reading into.

This basically started with this change :
/* Transaction */
struct __pmtrans_t {
- pmtranstype_t type;
pmtransflag_t flags;
pmtransstate_t state;
- alpm_list_t *packages; /* list of (pmpkg_t *) */
+ alpm_list_t *add; /* list of (pmpkg_t *) */
+ alpm_list_t *remove; /* list of (pmpkg_t *) */
And then I have to modify all the code accordingly.
This patch utilizes the power of sync.c to fix FS#3492 and FS#5798.
Now an upgrade transaction is just a sync transaction internally (in alpm),
so all sync features are available with -U as well:
* conflict resolving
* sync dependencies from sync repos
* remove unresolvable targets
See http://www.archlinux.org/pipermail/pacman-dev/2009-June/008725.html
for the concept.
We use "mixed" target list, where PKG_FROM_FILE origin indicates local
package file, PKG_FROM_CACHE indicates sync package. The front-end can add
only one type of packages (depending on transaction type) atm, but if alpm
resolves dependencies for -U, we may get a real mixed trans->packages list.
_alpm_pkg_free_trans() was modified so that it can handle both target types
_alpm_add_prepare() was removed, we use _alpm_sync_prepare() instead
_alpm_add_commit() was renamed to _alpm_upgrade_targets()
sync.c (and deps.c) was modified slightly to handle mixed target lists,
the modifications are straightforward. There is one notable change here: We
don't create new upgrade trans in sync.c, we replace the pkgcache entries
with the loaded package files in the target list (this is a bit hackish) and
call _alpm_upgrade_targets(). This implies a TODO (pkg->origin_data.db is
not accessible anymore), but it doesn't hurt anything with pacman front-end,
so it will be fixed later (otherwise this patch would be huge).
I updated the documentation of -U and I added a new pactest, upgrade090.py,
to test the syncdeps feature of -U.

If the user switches from unstable repo to a stable one, it is quite hard to
sync its system with the new repo (the user will see many "Local is newer
than stable" messages, nothing more). That's why I introduced -Suu, which
treats a sync package like an upgrade, iff the package version doesn't match
with the local one's.
I added a new pactest (sync104.py) to test this, and I updated the
documentation of -Su.
