The CheckSpace option checks the size of all files in a package being replaced
and gives a warning when it can not read the file. However, files in NoExtract
are expected to be missing and should not be warned about.
Fixes FS#47470.

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##' {} +

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.

Dan: move the #ifdef slightly so we don't have unused functions on
certain platforms (e.g., OS X).

With lazy loading in place, it's now quite obvious that we aren't

If one had a mountpoint at '/e' (don't ask), a file being installed to
'/etc' would map to it incorrectly. Ensure we do more than just prefix
matching on paths by doing some more sanity checks once the simple
strncmp() call succeeds.

Was able to get my hands on one of these boxes today, so add yet another
new way of doing this. I'm glad these calls are so standardized. This
was compile tested on Linux and Illumos and seems to still be working in
both places.

Ensures that config.h is always ordered correctly (first) in the
includes. Also means that new source files get this for free without
having to remember to add it.
We opt for -imacros over -include as its more portable, and the
added constraint by -imacros doesn't bother us for config.h.
This also touches the HACKING file to remove the explicit mention of
config.h as part of the includes.

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.

Put all the callback stuff in alpm.h in one spot, and make the following
renames for clarity with the new structure:
ALPM_TRANS_EVT_* --> ALPM_EVENT_*
ALPM_TRANS_CONV_* --> ALPM_QUESTION_*
ALPM_TRANS_PROGRESS_* --> ALPM_PROGRESS_*
alpm_option_get_convcb() --> alpm_option_get_questioncb()
alpm_option_set_convcb() --> alpm_option_set_questioncb()

This was just disgusting before, unnecessary to limit these to only
usage in a transaction. Still a lot of more room for cleanup but we'll
start by attaching them to the handle rather than the transaction we may
or may not even want to use these callbacks.

This accomplishes quite a few things with one rather invasive change.
1. Iteration is much more performant, due to a reduction in pointer
chasing and linear item access.
2. Data structures are smaller- we no longer have the overhead of the
linked list as the file struts are now laid out consecutively in
memory.
3. Memory allocation has been massively reworked. Before, we would
allocate three different pieces of memory per file item- the list
struct, the file struct, and the copied filename. What this resulted
in was massive fragmentation of memory when loading filelists since
the memory allocator had to leave holes all over the place. The new
situation here now removes the need for any list item allocation;
allocates the file structs in contiguous memory (and reallocs as
necessary), leaving only the strings as individually allocated. Tests
using valgrind (massif) show some pretty significant memory
reductions on the worst case `pacman -Ql > /dev/null` (366387 files
on my machine):
Before:
Peak heap: 54,416,024 B
Useful heap: 36,840,692 B
Extra heap: 17,575,332 B
After:
Peak heap: 38,004,352 B
Useful heap: 28,101,347 B
Extra heap: 9,903,005 B
Several small helper methods have been introduced, including a list to
array conversion helper as well as a filelist merge sort that works
directly on arrays.

from package files. Future patches will take advantage of this newly
available information, and frontends can use it as well.

Only one of these looked like a real red flag, in find_requiredby(), but
it doesn't hurt to fix several of them up anyway.
Unfortunately, we can't turn this on universally due to things like the
sync(), remove(), etc. builtins which we often use as variable names.
