Rather than using a string-based path, we can restore the working
directory via a file descriptor and use of fchdir().
From the getcwd manpage:
Opening the current directory (".") and calling fchdir(2) to
return is usually a faster and more reliable alternative when
sufficiently many file descriptors are available.

We did a lot of both malloc-ing and stack printing to form some paths in
this code. Attempt to unify it all into the one get_pkgpath() method by
adding an optional third "filename" parameter, and form the necessary
path string all in one go.

1. Don't run it if something failed in package removal- this mirrors
what we already do in sync transactions.
2. Don't run it if we are invoking it for the replaces removal bit of a
sync transaction- it doesn't make sense to run ldconfig halfway through
a sync install; we should only run it once at the end.

This shouldn't really be declared with const, and causes a compile error
when -Wcast-qual is used. Remove the const specifier from the function
specification and all implementations.
Also fix one other trivial -Wcast-qual warning in _alpm_db_cmp().

This function doesn't exist on OSX. Since there aren't any other
candidates in alpm for which this function would make sense to use,
simply replace the function call with a loop that does the equivalent.

Check for the existance of a partial download of a package file before
jumping to delta calculations. Currently, if there were 10MiB remaining
in a 100MiB the values passed to the front end do not reflect this.

This adjusts type usage to match POSIX provided types from
<sys/types.h> rather than assuming everything will fit in a long or
unsigned long. Use fsblkcnt_t (unsigned) and blkcnt_t (signed) as
appropriate. These are affected the same way off_t is on 32 bit
platforms, where the types are extende to 64 bits if large file support
is enabled.
Because most numbers here are block counts, this isn't
near as pressing as using a 32-bit variable for file sizes where
anything over 2GiB can burn you; we likely can support files at least
512 but mainly 4096 times larger.

Changes in commit dc3336c277 caused this to stop working as expected for
sync packages, due to the way the logic is structured. Ensure we always
enter the signature code if the bitflag is flipped on to check
signatures for packages. Rename 'use_sig' to 'has_sig' for clarity.

_alpm_filecache_setup() destroys the list of cachedirs when it finds no
writeable directories in the config. This put us in an awkward situation
where _alpm_filecache_find() would locate a downloaded file in a r/o
cachedir, but then fail to install it after _alpm_filecache_setup() is
called (with a NULL argument). Change this behavior to merely prepend
the temporary directory to the list of available cachedirs.
Dan exposed it in e07547ee4ed4, as now a package can be found in a
directory we may not be able to actually store packages in.

This was just disgusting before, unnecessary to limit these to only

We currently have csize, isize, and size concepts, and sometimes the
difference isn't clear. Ensure the following holds:
* size (aka csize): always the compressed size of the package; available
for everything except local packages (where it will return 0)
* isize: always the installed size of the package; available for all
three package types

We were using atol(), which on 32 bit, cannot handle values greater than
2GiB, which is fail.
Switch to a strtoull() wrapper function tailored toward parsing off_t
values. This allows parsing of very large positive integer values. off_t
is a signed type, but in our usages, we never parse or have a need for
negative values, so the function will return -1 on error.

This reduces from 5 to 3 the number of searches needed on the string
looking for a comparison operator, since we can so a second quick
comparison looking for '=' if we find '<' or '>'. It also makes every
search doable with strchr() or memchr() rather than the slower strstr()
method.
In testing, only 10% of splitdep calls (~1600 / 16000) during an -Ss
database load found a version comparison operator, so optimizing the not
found path to be require less work makes sense.

If we fell through to the ALPM_DEP_MOD_ANY case, ptr would be NULL, and
we would pass (0 - <str>), which is a rather large negative number or
bogus positive number, depending on signed/unsigned. Just use strdup in
the case where we don't have a ptr available.

Hard to believe there was still more room to improve on this, but I
found an easily correctable oversight tonight. Our databases (both sync
and local) contain many blank lines, and we were not moving onto the
next line right away in these cases; instead we would proceed through
our strcmp() conditional checks as normal.
Some local numbers follow to show the effects of this patch:
Sync `-Ss foobarbaz`:
71,709 blank lines skipped early
~1,505,889 strcmp() calls avoided (21 per line)
~15% speed improvement (.210 --> .179 sec)
Local `-Qs foobarbaz`:
6,823 blank lines skipped early
115,991 strcmp() calls avoided (17 per line)
~6% speed improvement (.080 -> .071 sec)

I was trying to take a shortcut and not introduce a wrapper struct for
the signature results, so packed it all into alpm_sigresult_t in the
first iteration. However, this is painful when one wants to add new
fields or only return information regarding a single signature.
Refactor the type into a few components which are exposed to the end
user, and will allow a lot more future flexibility. This also exposes
more information regarding the key to the frontend than was previously
available.
The "private" void *data pointer is used by the library to store the
actual key object returned by gpgme; it is typed this way so the
frontend has no expectations of what is there, and so we don't have any
hard gpgme requirement in our public API.

There were many cases where the string coming in was a blank line, e.g.
"\n\0", length 1. The trim routine starts by trimming leading spaces,
thus trimming everything. We would then proceed to do a memmove of the

instead.
