Tobias Stoeckmann bd4ed1ca02 libpkgconf: fileio: prevent buffer overflow. 
pkgconf_fgetline is called with a user-defined buffer, its size, and
a FILE stream to read input from.

If the buffer is almost completely filled and the file stream contains
an escaped character, then it is possible to trigger an off-by-one
buffer overflow with a '\0' character.

Easiest example to trigger this:

char buf[2];
pkgconf_fgetline(buf, sizeof(buf), stdin);

Enter "\\" (two backslashes) and press enter. If the library and the
program are compiled with address sanitizer, you will see the program
crashing. Otherwise it depends on your architecture what happens.

Since nobody should be using a buffer of only size 1 or 2, keep enough
space for a possibly escaped character in while loop by subtracting one
more byte for this situation, not just for '\0'.

fix the order of header includes 
config.h should be included before stdinc.h, otherwise large file
support is not enabled.

tuple: Ensure buf length is always >= 1 in dequote 
If a key is defined with no value, dequote will allocate a buffer with a
length of 0.  Since the buffer's length is 0, any manipulation of its
content is UB.

Example .pc file:

prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include

xcflags=
xlibs= -lSM -lICE  -lX11

Name: Obt
Description: Openbox Toolkit Library
Version: 3.6
Requires: glib-2.0 libxml-2.0
Libs: -L${libdir} -lobt ${xlibs}
Cflags: -I${includedir}/openbox/3.6 ${xcflags}

Output using pkgconf 1.5.2 on x86_64 Linux/musl:

% pkgconf --cflags obt-3.5
-I/usr/include/openbox/3.6 \�\\�I\�\ -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/libxml2

Leorize f36ccc1d91 libpkgconf: add support for Haiku 
client: use BELIBRARIES

On Haiku, BELIBRARIES is the equivalent to LIBRARY_PATH on many other
systems, while LIBRARY_PATH is instead the LD_LIBRARY_PATH of Haiku.

pkg: bootstrap package search paths with Haiku's find_paths

This commit adds build_default_pkgconfig_path. The function appends
to the list given the default pkgconfig paths, and will supersede
get_default_pkgconfig_path
