Florian Pritz cd2370754a Remove ts and sw from vim modeline when noet is set
Forcing vim users to view files with a tabstop of 2 seems really
unnecessary when noet is set. I find it much easier to read code with
ts=4 and I dislike having to override the modeline by hand.

Command run:
find . -type f -exec sed -i '/vim.* noet/s# ts=2 sw=2##' {} +

Dave Reisner e183522e31 diskspace: only load filesystem info on demand
Only load filesystem details for the mount points that we're actually
going to write to. This reduces our syscall count considerably. In the
case of installation, we would actually stat every mountpoint twice (an
extra round for download diskspace) which means (on my system) a total
of 60 syscalls to write to 3 partitions when installing the kernel
package. This change reduces the 60 syscalls down to the expected 3.

A slight debug output change is added here to discern between a
mountpoint added to our linked list versus when we actually load the fs
info.

Dave Reisner 6e29f02e94 diskspace: add _alpm_check_downloadspace()
This function determines if the given cachedir has at least the given
amount of free space on it. This will be later used in the sync code to
preemptively halt downloads.

Dan McGee 8ffa2b24a5 Use more correct integer types in diskspace checks
This adjusts type usage to match POSIX provided types from
<sys/types.h> rather than assuming everything will fit in a long or
unsigned long. Use fsblkcnt_t (unsigned) and blkcnt_t (signed) as
appropriate. These are affected the same way off_t is on 32 bit
platforms, where the types are extende to 64 bits if large file support
is enabled.

Because most numbers here are block counts, this isn't
near as pressing as using a 32-bit variable for file sizes where
anything over 2GiB can burn you; we likely can support files at least
512 but mainly 4096 times larger.

Dan McGee 30f338cce6 diskspace: allow used flag to be toggled for both remove and install
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.

Dan McGee 3afe3b6dfb Check mountpoint read-only status when checking space
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.

Dan McGee 942bb9e64a Skip diskspace checking for symlinks and directories in all cases
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.

Dan McGee b7015af0fc diskspace style cleanups and small fixes
* 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

Dan McGee ec136784d4 Refactor statfs/statvfs type check
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.
