This function returns and internalized dictionary from a package's metadata
plist file as specified by its arguments.
Update all code to use it where appropiate.
- There's no need to check rval for prop_dictionary_get_*, we are sure the
objects are there at prop_dictionary_set_* time.
- Avoid two chdir(2) calls per INSTALL/REMOVE run.
- Avoid using access(2) to check for existence of INSTALL/REMOVE scripts,
just try to run the executable directly and check for ENOENT.
Includes the following change:
* When replacing a package that is going to be updated in the transaction
do not remove it, just overwrite its files and continue. The updated
package will find that old files didn't match the SHA256 hash and will
skip them. This solves the issue of new package updates requiring new
dependencies with files that were previously stored in the old version.
For example gtk+-2.20 containing gdk-pixbuf, and gtk+-2.22 requiring
gdk-pixbuf externally.
* libxbps: improved xbps_get_file_hash() to mmap(2) rather than read(2)
the file we have to process. With mmap'ed files the hash can be
processed 5x faster than before, or even more in some cases.
* libxbps: switch to OpenSSL SHA256 implementation and remove the one
previously used. It's faster and OpenSSL is required for libfetch so
there is not point in using it.
Changes included in this set:
* Added strlcat() and strlcpy() from OpenBSD, always use them if the
system does not have them built in.
* Changed an array of PATH_MAX size allocated in the stack, to a dynamically
allocated buffer from heap. This should reduce memory usage a bit.
* Simplify code that implemented a homegrown realpath(3) implementation,
simply use realpath(3).
* If compiler supports -fstack-protector, build all code with
-D_FORTIFY_SOURCE=2 and --param ssp-buffer-size=1 so that all
buffers are protected.
* libxbps: while running INSTALL/REMOVE scripts, do not fail if a script
returns ENOENT but the script exists; that means the script did not match
the expected action on its switch statement and the fact can be simply
ignored.
* libxbps: while upgrading packages and searching for obsolete files,
do not remove the files that did not match previous SHA256 hash. Also,
only remove obsolete dangling symlinks.

* Add proplib-0.4.1 source and use it in XBPS. This is to avoid
an external dependency, so that we depend on the features of the
internal library. This also means that proplib is not required anymore.
* Added support to read/write gzip compressed plists by default, thanks
to proplib-0.4 that gained new functionality.
That means that from now, XBPS will be able to write compressed gzip
plist files for all metadata related work. This will vastly reduce
bandwidth required for fetching remote repo's pkg index file and
binary packages.

This helps to catch upgrade problems and simplifies some parts of the code.
Bumped XBPS_RELVER because xbps_remove_pkg() has been changed.

- use printf to print commands rather than echo, which it may not have
support for escape sequences (-e).
- Remove DESTDIR from SBINDIR, MANDIR, LIBDIR and INCLUDEDIR so that
you can override it.
