This gives us a bit more control and over the archive reading process,
and a bit less is done behind the scenes. It also allows us to use
fstat() in preference to stat(), which should avoid some potential race
conditions.
Some reorganization is necessary to move the stat calls after the open()
calls. Error handling and cleanup in general is also improved, as we had
several potential memory and file handle leaks before in some error
paths.

This takes the place of three previously used constants:
ARCHIVE_DEFAULT_BYTES_PER_BLOCK, BUFFER_SIZE, and CPBUFSIZE.
In libarchive 3.0, the first constant will be no more, so we can ensure
we are forward-compatible by removing our usage of it now. The rest are
unified for consistency.
By default, we will use the value of BUFSIZ provided by <stdio.h>, which
is 8192 on Linux. If that is undefined, a default value is provided.

There aretwo seperate issues in the same block of file conflict
checking code here:
1) If realpath errored, such as when a symlink was broken, we would call
'continue' rather than simply exit this particular method of
resolution. This was likely just a copy-paste mistake as the previous
resolving steps all use loops where continue makes sense. Refactor
the check so we only proceed if realpath is successful, and continue
with the rest of the checks either way.
2) The real problem this code was trying to solve was canonicalizing
path component (e.g., directory) symlinks. The final component, if
not a directory, should not be handled at all in this loop. Add a
!S_ISLNK() condition to the loop so we only call this for real files.
There are few other small cleanups to the debug messages that I made
while debugging this problem- we don't need to keep printing the file
name, and ensure every block that sets resolved_conflict to true prints
a debug message so we know how it was resolved.
This fixes the expected failures from symlink010.py and symlink011.py,
while still ensuring the fix for fileconflict007.py works.

These should all prevent installation, and yet two of the three tests
currently fail. Not good.
The best way to see what is going on here is to diff the three new tests
side by side- there is only a small difference between the three tests,
and that is in the destination of the symlink in question that should
never be overwritten.
symlink010.py: myprogsuffix -> myprog
symlink011.py: myprogsuffix -> broken

There is some pecular behavior going on here when a package is loaded
that has no files, as is very common in our test suite. When we enter
the realloc/sort code, a package without files will call the following:
files = realloc(NULL, 0);
One would assume this is a no-op, returning a NULL pointer, but that is
not the case and valgrind later reports we are leaking memory. Fix the
whole thing by skipping the reallocation and sort steps if the pointer
is NULL, as we have nothing to do.
Note that the package still gets marked as 'files loaded', becuase
although there were none, we tried and were successful.

First, use fstat() in preference to stat() since we already have an open
file handle. This also removes the need to check for a symlink as that
is not possible when a file is opened.
Next, use archive_entry_mode() rather than archive_entry_stat() as we
only use the mode portion of the stat struct and the call is much
cheaper. Also delay it until it is necessary.

This adds a logger to the CURLE_OK case so we can always know the return

On -R operations, the "New Version" column is always empty, taking up
space and not really showing the user anything valuable. The same is
true on -S or -U operations for the "Old Version" column when packages
are only being installed and not upgraded.
Remove this column so we get a few screen columns back, especially now
that we show repo/packagename style output. This also makes some
adjustment to the padding logic. We no longer include padding in column
widths but it is included in the total table width. We also ensure the
last displayed column is always right aligned, even if this is not the
actual rightmost column.

Now that pm_printf() always prints to stderr, we don't need this second

The absolutely terrible part about this is the failure on GPGME's part
to distinguish between "key not found" and "keyserver timeout". Instead,
it returns the same silly GPG_ERR_EOF in both cases (why isn't
GPG_ERR_TIMEOUT being used?), leaving us helpless to tell them apart.
Spit out a generic enough error message that covers both cases;
unfortunately we can't provide much guidance to the user because we

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 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.
