Allan McRae bb4d2b72c1 Do not use full path for ldconfig
The ldconfig binary is not guaranteed to be in /sbin. Change to calling
just "ldconfig" rather than using the full path.

This removed the check that the ldconfig binary exists. However, it is
a reasonable assumption that it will exist if its configuration file
does.

Allan McRae 27d9c25ee2 Split common utility functions for libalpm and pacman
There is duplicated code in the util.c files in the libalpm and pacman
source code. Split this into a separate file so that it can be shared
via a symlink. This prevents code divergence between the two code bases.

Also, move mbasename and mdirname from pacman/util.c into util-common.c
in preparation for the following patch that uses them to add an extension
to pacsave files.

Dave Reisner ddbd36103d util: fix line length calc in _alpm_archive_fgets
74274b5dc3 which added the real_line_size to the buffer struct
didn't properly account for what happens when archive_fgets has to loop
more than once to find the end of a line. In most cases, this isn't a
problem, but could potentially cause a longer line such as PGP signature
to be improperly read.

This patch fixes the oversight and focuses on only calculating the line
length when we hit the end of line marker. The effective length is then
calculated via pointer arithmetic as:

  (start_of_last_read + read_length) - start_of_line

Dan McGee 5a9f5c60da Convert ALLOC_FAIL macro into a function
This path is rarely (read: never) taken in any normal run of the code,
so injecting the fprintf() call everywhere with the macro is a bit
overkill. Instead, add a lightweight _alpm_alloc_fail() function that
gets called instead.

This does have a reasonable effect on the size of the generated code;
most places using the macros provided by util.c have their code size
reduced.

pacman -U <pkg> returns a bogus "could not find or read package" if the
file is on a fuse file system that doesn't allow root access. Debug
output isn't very helpful here either so we should log why the access
check failed.

The other 2 checks already log something when failing so logging a more

Dan McGee 7f51ba99ae Fix segfaults on opening invalid archive files
"invalid" in this case simply means files that may or may not be
archives. Discovered via a `pacman -Sc` operation with delta files in
the package cache directory, but can be triggered if any file is passed
to `pacman -Ql` that isn't an archive, for instance, or if the sync
database file is not an archive.

Fix it up so we are more careful about calling archive_read_finish()
only on archives that are valid and have not already been closed, and
teach our archive open function to set the returned archive to NULL if
we aren't going to be returning something valid anyway.

Dan McGee dee8144ce5 Add helper method for creating and opening archive object
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.

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.
