BPackageInfo::Parser: Validate URL strings.

Fixes #12710.

Signed-off-by: Augustin Cavalier <waddlesplash@gmail.com>
I fixed the modifications to the Jamfiles in src/bin, they were all wrong
in the patch.

package kit: Add API for parsing resolvable expression strings

* Add BPackageInfo::ParseResolvableExpressionString().
* Add BPackageResolvableExpression constructor and SetTo() taking an
expression string.

package info parser: improve string parsing

* Instead of two string token types (TOKEN_WORD, TOKEN_QUOTED_STRING),
there's now only one (TOKEN_STRING). Whether the string meets the
criteria is checked where needed. In most cases the check was already
done or not necessary anyway.
* Strings can now consist of an arbitrary sequence of quoted and
unquoted strings and escaping is also supported in unquoted string
segments.
* Among other things this fixes incorrect restrictions for resolvable
names and should also make quoting paths superfluous (unless they
contain separator characters).

hpkg format: Generalize user/global settings file attributes

* For all identifiers: Rename global settings file to global writable
file. We want to use the respective attribute also for other writable
files, not only settings files.
* User settings file/global writable file info/attribute: Add
isDirectory property/child attribute. This allows declaring global/
user settings directories associated with the package.

hpkg format: Add attributes for declaring users and groups

Move package info parser to its own file
