Prior to this commit, the code path responsible for prefix redefinition
(motivated by --define-prefix or otherwise) was visited more than
once, specifically since the check ignored pkg->owner->prefix_varname.
The current approach was to parse the .pc and, detect the prefix, throw
everything together and at the end replace all \ with / to not produce invalid
escape sequences.
This has the problem that escaping in .pc files is ignored and no longer
possible. Also in case the prefix path has a space in it the result would be
invalid because of missing escaping.
This changes the following things:
* We no longer normalize values at the end. Instead we assume .pc files use "/"
as a directory separator or "\\", same format as under Unix. "\" alone no
longer works. This shouldn't be a problem since most build tools produce .pc
files with "/" like meson, cmake, autotools.
* When injecting the prefix at runtime we convert the prefix to use "/" and
escape spaces so that in combination with the .pc content the result is a
valid escaped path value again.
This patch has been used in MSYS2 for some months now.
See #212
In case the version string has no whitespace then strcspn() returns
strlen() of the input, so whitespace is only found if len != strlen.
This fixes invalid warnings when parsing version fields.
If a file with a matching "uninstalled" name exists but cannot be
parsed, an invalid memory area is accessed.
How to reproduce:
$ touch poc-uninstalled.pc
$ PKG_CONFIG_PATH=. pkgconf poc
Windows allows both \ and / as valid path characters. A computed path
such as C:\development\libfoo\pkgconfig/foo.pc will result in a computed
pkgconf_pkg_t.id of "pkgconfig/foo".
Accordingly, correct the path normalization for checking for / after
the \ path has been dealt with in all cases.
Every version line has a newline at the end; the malformed whitespace checker
should just check for trailing spaces and tabs.

This fixes a problem where on Windows the prefix would
not match if the prefix is generated with backslashes
and the rest of the variables use normal slashes
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
in almost all cases, we partially solve the dependency graph multiple times, which
just wastes resources. if we record the solution to a given dependency node, further
iterations can make use of the previous solution without having to solve it again.
this is safe because all provides entries (including virtuals) are knowable prior to
solving the dependency graph the first time.
a nice side effect of this is that all packages are preloaded when querying
information about them (--cflags and related commands).
