This sets curl's CURLOPT_PINNEDPUBLICKEY option in the built-in
downloader, or replaces %p in XferCommand. This pins public
keys to ensure your TLS connection is not man-in-the-middled
without relying on CAs etc. Probably most useful currently
for very small or single groups of servers.
It would obviously be best as a per-mirror option, but such
a thing currently does not exist.

This allows functions which return an _alpm_errno_t to always return a
genuine _alpm_errno_t for consistency, even in cases where there are
no errors. Since ALPM_ERR_OK = 0, their callers can still simply check
'err = some_fn(); if (!err) { ... }'.

Curl 7.32.0 added CURLOPT_XFERINFOFUNCTION, which deprecates
CURLOPT_PROGRESSFUNCTION and means less casting doubles to size_ts for
alpm. This change has no user-facing nor frontend-facing effects.

When curl calls alpm's dlcb, alpm calls the frontend's cb with the
following (dlsize, totalsize) arguments:
0, -1: initialize
0, 0: no change since last call
x {x>0, x<y}, y {y>0}: data downloaded, total size known
x {x>0}, x: download finished
If total size is not known, do not call frontend cb (no change to
original behavior); alpm's callback shouldn't be called if there is a
download error.

On filesize exceeded error pacman leaves a .part file in cache dir,
resulting in this error on next try:
error: failed to commit transaction (wrong or NULL argument passed)
Errors occurred, no packages were upgraded.
Unlink the file on error to avoid this.
When a package is already partially downloaded in the cache, its download
size will only be of what's left to be downloaded. Since pkg->download_size
is what's used when calculating the total download size for the totaldl
callback, same thing apply.
However, the download progress callback was including this initial size,
which would thus lead to invalid values (and percentage) used in frontends.
That is, the progress bar could e.g. go further than 100%
In the case of pacman, there is a sanity check for different historical
reason (44a57c89), so before the possible "overflow" was noticed, the total
download size/progress reported was wrong. Once caught, the TotalDownload
option was ignored and it would use individual file download values as
fallback instead.

If the server redirects from ${repo}.db to ${repo}.db.tar.gz pacman gets
this wrong: It saves to new filename and fails when accessing
${repo}.db.
We need the remote filename only when downloading remote files with
pacman's -U operation. This introduces a new field 'trust_remote_name'
to payload. If set pacman downloads to the filename given by the server.
The field trust_remote_name is set in alpm_fetch_pkgurl().
Fixes FS#36791 ([pacman] downloads to wrong filename with redirect).

On operating systems we support, the behavior is always such that the
kernel will do the right thing as far as invalidating the file
descriptor, regardless of the eventual return value. Therefore,
potentially looping and calling close multiple times is wrong.
At best, we call close again on an invalid FD and throw a spurious EBADF
error. At worst, we might close an FD which doesn't belong to us when a
multi-threaded application opens its own file descriptor between
iterations of the loop.

RFC 2616 doesn't forbid a 301 or 302 repsonse from having a body, and
servers exist in the wild that show this behavior. In order to prevent
pacman from showing a progress bar when we aren't actually downloading a
package (and merely following one of these pain in the butt redirects),
capture the server response code in the response header, rather than
waiting to peel it off the handle after the download has finished.

It can happen that the to-be-downloaded file cannot be created in cachedir.
For example, I am an -Sup user, and it is comfortable to set --cachedir to
/mnt/pendrive, which is a FAT filesystem, so files like
capseo-1:0.3-2-i686.pkg.tar.xz cannot be downloaded to there.
Before this patch, pacman didn't give clear output about what happens when
the download code could not create the necessary file. This can be confusing
with -Su. An example output:
***
$ sudo pacman -S capseo bochs --cachedir /c/TEMP

After the patch, pacman will give more informative error message (and
pm_errno is set properly):
***

error: failed to commit transaction (failed to retrieve some files)
***
Unfortunately, the "could not open file" error message is printed for
every mirror (that can be dozens of lines), which is ugly, but at least
informative... Without modifying the download logic (for example, by
introducing -2 return value for _alpm_download() to indicate giving up),
this ugliness cannot be eliminated.

This is in the realm of "probably not going to happen", but if someone
were to translate "disk" to a string longer than 256 characters, we
would have a smashed/corrupted stack due to our unchecked strcpy() call.
Rework the function to always length-check the value we copy into the
hostname buffer, and do it with memcpy rather than the more cumbersome
and unnecessary snprintf.
Finally, move the magic 256 value into a constant and pass it into the
function which is going to get inlined anyway.
