Turn it into an enum rather than a boolean, and use a bitmask like we do for
reading DB entries. The relevant flag is turned on in our two calculate
loops, and anything reading the used flag later can decided which flag (or
either) is relevant.
This will allow the read-only partition code to be triggered on a
remove-only operation, e.g. if /boot was read-only and one tried to remove
grub in a sync transaction. Of course, right now, we don't actually run the
diskspace check code in the '-R' codepath.

This is a bit of a stopgap solution for the problem, but an easier one than
revamping the file conflict checking code to support the same stuff. Using
some more gross autoconf magic, figure out which struct field we need to
look at to determine read-only status and store that on our mountpoint
struct. If we find out we needed this partition after calculating size
requirements, then toss an error.

We did this in some but not all cases, assuming the 0 value coming out of
libarchive would not be a problem. However, this does not work for "fake"
filesystems such as rpc_pipefs, which reports a free block and total block
count of zero.
Fix this by not ever counting symlinks or directories, and adding a note
explaining that if we someday do count directories, their size needs to be
attributed to the proper place.
This patch also includes a few cleanups/performance tweaks- avoid calling
strlen() on the mountpoint directory string as much by storing this size in
our mountpoint struct, and push the snprintf() call up to the calculate
functions since we were already doing it here in the remove case.

* Use our normal return() function syntax
* Rework a few things to reduce number of casts
* Fix void function argument declaration
* Add missing gettext _() call
* Remove need for seperate malloc() of statvfs/statfs structure
* Unify argument order of static functions- mountpoints now always
passed first
* Count all files that start with '.' in a package against the DB
* Rename db to db_local in check_diskspace to clarify some code
* Fix some line wrapping to respect 80 characters

Turn it into a configure-type typedef, which allows us to reduce the
amount of duplicated code and clean up some #ifdef magic in the code
itself. Adjust some of the other defined checks to look at the headers
available rather than trying to pull in the right ones based on
configure checks.

Add a mount_point_list() function that attempts to portably obtain
a list of system mount points and a struct to hold needed mount point
information.
Abort the transaction if we are unable to determine the mount points.

Very basic prototyping for adding functionality to check free disk
space before performing package installs.
