Rework the frontend and backend to allow passing a ratio value in for
UseDelta rather than having a hardcoded #define-d 0.7 value always used.
This is useful for those with fast connections, who would likely benefit
from tuning this ratio to lower values; it is also useful for general
testing purposes.
The libalpm API changes for this, but we do support the old config file
format with a no-value 'UseDelta' option; in this case we simply use the
old default of 0.7.
We clamp the ratio values to a sane range between 0.0 and 2.0, allowing
ratios above 1.0 for testing purposes.

Ensures that config.h is always ordered correctly (first) in the
includes. Also means that new source files get this for free without
having to remember to add it.
We opt for -imacros over -include as its more portable, and the
added constraint by -imacros doesn't bother us for config.h.
This also touches the HACKING file to remove the explicit mention of
config.h as part of the includes.

When doing a bare -U operation on a local package that doesn't pull in
any dependencies from the sync databases, we can get away with missing
database files. This makes the check conditional on no sync targets
found in the target list. This is not the prettiest code here so we have
a bit of hackish behavior required to straighten both the behavior and
the nonsensical error message out.

If you need zero-filled allocations, call CALLOC() instead.

This was done to squash a memory leak in the sync database download
code. When we downloaded a database and then reused the payload struct,
we could find ourselves calling get_fullpath() for the signatures and
overwriting non-freed values we had left over from the database
download.
Refactor the payload_free function into a payload_reset function that we
can call that does NOT free the payload itself, so we can reuse payload
structs. This also allows us to move the payload to the stack in some
call paths, relieving us of the need to alloc space.
Signed-off-by: Dan McGee <dan@archlinux.org>
Rather than free them right away, keep the list on the transaction as
we already do with add and remove lists. This is necessary because we
may be manipulating pointers the frontend needs to refer to packages,
and we are breaking our contract as stated in the alpm_add_pkg()
documentation of only freeing packages at the end of a transaction.
This fixes an issue found when refactoring the package list display
code.

In the sync code, we explicitly allocated a string for this field, while
in the dload code itself it was filled in with a pointer to another
string. This led to a memory leak in the sync download case.
Make remote_name non-const and always explicitly allocate it. This patch
ensures this as well as uses malloc + snprintf (rather than calloc) in
several codepaths, and eliminates the only use of PATH_MAX in the
download code.

This moves the result processing out of the validation check loop itself
and into a new loop. Errors will be presented to the user one-by-one
after we fully complete the validation loop, so they no longer overlap
the progress bar.
Unlike the database validation, we may have several errors to process in
sequence here, so we use a function-scoped struct to track all the
necessary information between seeing an error and asking the user about
it.
The older prompt_to_delete() callback logic is still kept, but only for
checksum failures. It is debatable whether we should do this at all or
just delegate said actions to the user.

This allows us to do all delta verification up front, followed by

* Move is_local standalone field to status enum
* Create VALID/INVALID flag pair
* Create EXISTS/MISSING flag pair
With these additional fields, we can be more intelligent with database
loading and messages to the user. We now only warn once if a sync
database does not exist and do not continue to try to load it once we
have marked it as missing.
The reason for the flags existing in pairs is so the unknown case can be
represented. There should never be a time when both flags in the same
group are true, but if they are both false, it represents the unknown
case. Care is taken to always manipulate both flags at the same time.

This reverts some hacky behavior from 5fc3ec and resets the handle's

Previously, the behavior was such that if a sync operation required
packages from multiple repos, a download error in the first repo would
cause a hard repo, ignoring the remainder of the repositories. Change
this behavior so that we do a better job of fetching as many packages as
possible before aborting the transaction.
There's a little bit of refactoring mixed in here to get rid of some
useless variables. Since we now depend heavily on the value of
handle->pm_errno being accurate the determine the function's return
value, we clear it when the transaction state is set.

We did this with depends way back in commit c244cfecf6 in 2007. We
can do it with these fields as well.
Of note is the inclusion of provides even though only '=' is supported-
we'll parse other things, but no guarantees are given as to behavior,
which is more or less similar to before since we only looked for the
equals sign.
Also of note is the non-inclusion of optdepends; this will likely be
resolved down the road.
The biggest benefactors of this change will be the resolving code that
formerly had to parse and reparse several of these fields; it only
happens once now at load time. This does lead to the disadvantage that
we will now always be parsing this information up front even if we never
need it in the split form, but as these are uncommon fields and our
parser is quite efficient it shouldn't be a big concern.
