Fix for sync044.py and reason001.py.
Rename sync->data to sync->removes (alpm_list_t *)
Replace pmsynctype_t sync->type by pmpkgreason_t sync->newreason
The type field was set to UPGRADE or DEPEND or REPLACE.
Instead of using type = UPGRADE or DEPEND, we now rather use a
"pmpkgreason_t newreason" field directly (= explicit or depend) which allows
a better handling of the install reason.
And the REPLACE type is now deduced implicitly when the sync->removes list
is not empty.

The original patch from Nagy tried to resolve target vs target conflicts,
and so broke the following pactests : sync040, sync041 and sync990
Nagy's proposal to solve this situation was to choose the interactive way,
ask the user how to deal with it: either remove pkg1 or remove pkg2 or stop
here. So he left this as a TODO.
But instead of trying to resolve these conflicts or asking the user, I
tried to find a more conservative way, looking at what the current pactests
expected:
If between the two conflicting packages, one provides the other, pacman
will keep that one and remove the other from the target list. That breaks
sync893 and sync897. But Dan agreed these two looked weird and should be
changed.
This commit should close FS#8897, FS#8899 and FS#9024.

During a pacman operation such as a group install, pacman can ask several
questions such as "local version is up to date. Upgrade anyway?". They are
usually all answered either by yes or by no:
* yes when you want to reinstall all the targets.
* no when you only want to install the missing ones (either because you are
installing a group, or because you are copying a pacman -S line from wiki or
whatever).
So instead of asking this question for each target, it is now now configured
with a flag. Yes will be the default -S behavior, No will be achieved with
the --needed flag.

pmdepmissing_t was used for two totally different things :
missing dependencies, and dependency conflicts.
So this patch simply adds a type for dep conflicts,
and convert the code to use it.
This fix the TODO in conflict.c :
/* TODO WTF is a 'depmissing' doing indicating a conflict? */
Additionally, the code in conflict.c now eliminates the duplicated conflicts.
If pkg1 conflicts with pkg2, and pkg2 conflicts with pkg1, only one of them will be stored.
However the conflict handling in sync_prepare (sync.c) is still very asymetrical, and very ugly too.
This should be improved in the future (there is already a pending patch from Nagy that cleans it a lot).

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

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)
