We can take a large shortcut here that saves us a lot of time,
especially when upgrading packages with lots of directories. Obviously
iterating the full file list of every single package to determine if
this directory was present in any other package can take quite some time
on a system with many packages installed. We don't need to remove a
directory at all if we are upgrading a package and the version we are
moving to still had the directory.
Also make a small optimization on the package comparsion- we really only
care about equality here, not the result of the compare, so we can
shortcut using our name_hash.
What kind of benefit does this give us? Oh, only a reduction from 295.7
million to 1.4 million strcmp() calls (99.5% fewer) during a
`pacman -S linux libreoffice-common` operation.

This is not something that should be used on a frequent basis, and
giving it a short option encourages use without making the drawbacks
obvious. For the 1% of situations that require it, the 5 extra

This replaces several printf calls of the following styles:
printf("%s", ...);
printf("some fixed string");
printf("x");
We can use either fputs() or putchar() here to do the same thing
without incurring the overhead of the printf format parser.
The biggest gain here comes when we are calling the print function in a
loop repeatedly; notably when printing local package files.

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.

Replace "/tmp" with "${TMPDIR:-/tmp}" to allow for overriding the
hardcoded path.
Since we only use "/tmp" in conjunction with mktemp(1), we could also
have used "--tmpdir", which is GNU-ish, however (and the BSD counterpart
"-t" has been deprecated in GNU mktemp).

This includes some fixes to the messages that are displayed when a
signal is caught in makepkg or repo-add:
* Instead of always showing "==> ERROR: TERM signal caught. Exiting...",
replace "TERM" by whatever signal is actually caught.
* Fix a typo in the SIGERR error message in repo-add ("occurred" instead
of "occured"). Francois already fixed this for makepkg in 1e51b81c.

There is a small chance that a user sends SIGINT (or any other signal
that is trapped) when we're already in clean_up() which used to lead to
trap_exit() being executed and the remaining code in clean_up() being
skipped due to the bash signal/trap handler blocking EXIT (since its
handler is already being executed, even if it's interrupted).
In practice, this behaviour caused unexpected results (primarily because
pressing ^C at the wrong time left a lock file behind):
$ ./repo-add extra.db.tar.gz foobar
==> Extracting database to a temporary location...
^C
==> ERROR: Aborted by user! Exiting...
$ ./repo-add extra.db.tar.gz foobar
==> Extracting database to a temporary location...
==> ERROR: File 'foobar' not found.
==> No packages modified, nothing to do.
^C
==> ERROR: Aborted by user! Exiting...
$ ./repo-add extra.db.tar.gz foobar
==> ERROR: Failed to acquire lockfile: extra.db.tar.gz.lck.
==> ERROR: Held by process 18522
Fix this and reduce the chance of race conditions in signal handlers by:
* Unhooking all traps in both clean_up() and trap_exit().
* Call clean_up() explicitly in trap_exit() to make sure we remove the
lock file and the temporary directory even if we send SIGINT when
clean_up() is already being executed but didn't reach the unhook code
yet.
Also, add an optional parameter to clean_up() to allow for setting an
explicit exit code when we call clean_up() from trap_exit().

Instead of iterating character by character, use memchr() calls to
hopefully speed up the search. A newline is the most likely culprit, so
search for that first followed by a NULL byte if there was no newline in
the buffer.

In the default configuration, we can enter the signing code but still
have nothing to do with GPGME- for example, if database signatures are
optional but none are present. Delay initialization of GPGME until we
know there is a signature file present or we were passed base64-encoded
data.
This also makes debugging with valgrind a lot easier as you don't have
to deal with all the GPGME error noise because their code leaks like a
sieve.

This had the unfortunate implementation detail that depended on the
strings having 1 byte == 1 column hold true. As we know, this is not at
all the case once you move past the base ASCII character set.
Reimplement this whole thing so it doesn't depend on format strings at
all. Instead, simply calculate the max column widths, and then when
displaying each row add the correct amount of padding using UTF-8 safe
string length functions.

This will always be a 64-bit signed integer rather than the variable length

Similar to what we did in edd9ed6a, disconnect the relationship with our
stack allocated error buffer from the curl handle. Just as an FTP
connection might have some network chatter on teardown causing the
progress callback to be triggered, we might also hit an error condition
that causes curl to write to our (now out of scope) error buffer.

This allows for specifying an alternate configuration file path, similar
to pacman's "--config" option.
Given that there is currently no other way to tell pactree to read from
another configuration file (except for patching or symlinking), this
seems totally sensible - even if there are plans to refactor and/or
replace the standalone configuration file parser.
We do not define a short option for the sake of consistency with
pacman's set of command line options.
