This moves the common setup code of about 5 different callers into one
method. Error messages will now be common and shared in all places;
several paths did not have any messages at all before.
In addition, we now pick an ideal block size for the archive read based
off the larger value of our default buffer size or the st.st_blksize
field. For a filesystem such as NFS, this is often much larger than the
default 8192- values such as 32768 and 131072 are common.

When doing a bare -U operation on a local package that doesn't pull in
any dependencies from the sync databases, we can get away with missing
database files. This makes the check conditional on no sync targets
found in the target list. This is not the prettiest code here so we have
a bit of hackish behavior required to straighten both the behavior and
the nonsensical error message out.
Addresses FS#26899.

The point of this early compare to NULL byte check was so we could bail
early and skip the strcmp() call. Given we weren't doing the check
right, this never exited early. Fix it to work as intended.

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.

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.
