alpm_list_add always returns the provided list making it impossible for
callers to check whether or not the operation actually succeeded without
manually comparing the list length before and after. alpm_list_append
instead returns a pointer to the newly created list item so that success
can be checked.

The test introduced herein illustrates a behavior that may be unexpected
to package writers.
It creates a package "pkg3" that is configured to depend on a
"dependency" which version is between 3 and 4, inclusive. Two other
packages are already present, providing "dependency" in version 2 and 5,
respectively. So, the situation looks roughly like this:
pkg1 pkg3 pkg2
provides depends on provides
| <------------> |
version __________2____________3____________4____________5___________...
This seems to be enough to satisfy pacman when installing "pkg3". From
an iterative standpoint, this is completely logical: First, the
requirement "dependency>=3" is checked. There is a package that
satisfies this restriction, it is called "pkg2". Afterwards,
"dependency<=4" is covered in the same way by "pkg1".
Nonetheless, what a package writer intends when specifying
depends=('dependency>=3' 'dependency<=4')
is most probably that pacman should only allow this package to be
installed when there indeed is a package present that provides a version
of "dependency" that lies _between_ 3 and 5.

The signedness of char is implementation defined. On systems where
char is unsigned, comparing a variable of type char with -1 is never
true, due to integer promotion rules. To avoid this, introduce a
define for invalid field separators where -1 is cast to char. This will
ensure that the return value check works for both unsigned and signed char.
Fixes one warning [-Wtype-limits] for comparissons with -1 when compiling
with -funsigned-char.

The signedness of char is implementation defined. Since the
alpm_graph state is clearly meant to be signed, make the
signedness explicit.
This fixes bugs on systems where char is unsigned, in comparissons
of the following type:
if(v.state == -1)
which, if state is unsigned, will never be true due to integer
promotion rules.

There is no need to run any/remaining pre-transaction hooks as soon as a failure
has occured, which will lead to aborting the transaction.
So if an error occured during the first phase (reading directories/parsing
files), or as soon as a hook flagged abort_on_fail does fail, we stop processing
them and return.
(For post-transaction hooks, all hooks are run regardless since there's no
aborting.)

Signature downloading and DB validation was being based on the most
recent download status for the DB. If a DB successfully downloaded but
a signature did not, db_update would move to the next server. If the
next server tried does not have a more recent copy of the DB, db_update
would not download the DB again and would forget that the DB had
previously been updated. In this case it would skip validation
entirely, leaving an updated DB with the original validation status.
