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
NULL byte, which is completely worthless as we can just assign it
instead.

We had this interesting set of facts conundrum, according to vercmp
return values:
2.0a < 2.0
2.0 < 2.0.a
2.0a == 2.0.a
This introduces a code change that ensures '2.0a < 2.0.a' as would be
expected by the first two comparisons. Unfortunately this stays us a bit
further from upstream RPM code, but those are the breaks (in RPM, the
versions involving 'a' do in fact compare the same, but they are both
greater than the bare '2.0').

This is a refactor and refresh of the code used to find where we should
download packages.
* Incorporate suggestions from FS#25435 to use TMPDIR from the
environment if set, otherwise fall back to /tmp as before.
* Make the writability tests a bit more in depth. We now do a three part
check consisting of:
- S_ISDIR(): is this even a directory
- access(W_OK): is this directory writable by the current user.
Unfortunately for root, this almost always returns that it is, but
in the case of a RO mount or NFS share inaccessible to root, this
check will exclude the directory.
- mode & (any write bit): is there a writable bit set on this
directory. This makes it possible to enforce a read-only cache
directory by setting permissions to 0555, for example.

This changes the signature of _alpm_pkg_dup() to return an integer error
code and provide the new package in a passed pointer argument. All
callers are now more robust with checking the return value of this
function to ensure a fatal error did not occur.
We allow load failures to proceed as otherwise we have a chicken and egg
problem- if a 'desc' local database entry is missing, the best way of
restoring said file is `pacman -Sf --dbonly packagename`. This patch
fixes a segfault that was occurring in this case.
Fixes the segfault reported in FS#25667.
