Log message:
Simply and speed up buildlink3.mk files and processing.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

Log message:
Update to uriparser-0.7.3.  Adds a missing NULL check in
parsing routines.  Also, they ship doxygen-generated qt help
files, but installing those will require a seperate docs package
or doxgen option to avoid the large dependency.

Log message:
Update to uriparser-0.7.2.  Important reliability (crash/memory leak)
fix:

2008-09-01 -- 0.7.2

  * Fixed: Bad cleanup logic in functions
      - uriAddBaseUri(..)
      - uriRemoveBaseUri(..)
      Previously you needed to call uriFreeUriMembers on return code
      URI_ERROR_MALLOC and only then. So that's why these functions now
      take cleanup off your shoulders. An extra call to uriFreeUriMembers
      from your side is still needed in case of success.

Log message:
Update to 0.7.1.

2008-04-27 -- 0.7.1

  * Fixed: Bogus syntax error when parsing URIs with port-like
      passwords, e.g. "http://user:21@host/" (#1948038)
      Thanks to Friedrich Delgado Friedrichs for reporting!
  * Fixed: Parser did not handle trailing slashes correctly in some cases,
      which also made the structures produced from parsing "http://e.com/"
      and "http://e.com" indistinguishable. (#1950126)
      Thanks to Edward Z. Yang for reporting!

2008-04-04 -- 0.7.0

  * Added: Dissection and composition of query strings
  * Added: Documentation improvements
      (in|out|inout indicators, addition of \since and \see)
  * Changed: Code::Blocks project files updated from file format
      version 1.4 to 1.6, which is produced by Code::Blocks 8.02
  * Added: Code::Blocks workspace file
  * Changed: Soname set to 1:5:0

2008-02-25 -- 0.6.4

  * Added: Syntax-based normalization can now handle relative URIs,
      e.g. "../../a/b/.././c" is normalized to "../../a/c"
  * Fixed: Normalization code could free foreign memory
  * Fixed: Normalization processed the path segment even when asked not to
  * Added: MinGW Makefile and related readme
      Thanks to Michael Anthony Puls II!
  * Fixed: Documentation bug not requiring enough memory for the output
      buffer when converting a relative file URI back to a filename
  * Changed: Soname set to 1:4:0

2008-02-11 -- 0.6.3

  * Fixed: Two major crash bugs in normalization code
      Thanks to Adrian Manrique for the patch!
  * Added: Brief usage tutorial
  * Changed: Soname set to 1:3:0

2008-02-08 -- 0.6.2

  * Fixed: Freeing a normalized URI like "http://test?"
      caused a crash. Thanks to Adrian Manrique for reporting!
  * Fixed: Filename <--> URI string conversion helpers can
      now handle relative URIs and filenames
  * Changed: Soname set to 1:2:0

2007-12-23 -- 0.6.1

  * Fixed: Percent-encodings in hostnames were not repaired during
      normalization.
      Thanks to Adrian Manrique for reporting!
  * Fixed: Percent-encodings were fixed after dot removal not before during
      normalization.
      Thanks to Adrian Manrique for reporting!
  * Fixed: Include path order bug
      Thanks to Ed Schouten for reporting this!
  * Fixed: Shadow builds now possible
      Thanks to Adeodato Simó for the patch!
  * Added: Version guards for Autoconf/Automake
      Thanks to Martin Michlmayr for reporting!
  * Changed: Soname set to 1:1:0
