Various restructure of test framework handling of paths to avoid duplicate path editing which caused failed tests. Adjust many tests to deal with added subdirectories in build outputs now that toolset requirements are active.
Related changes:
* BoostBuild.Tester & TestCmd.TestCmd interfaces now accept external process parameters as a list of strings, thus avoiding problems with parsing arguments containing spaces.
* Avoided a potential process hang in case an external process being run prints out enough output to fill up the OS's pipe buffer (OS would pause the process until someone read the data from the pipe but the testing framework would not do this until the process in question had terminated).

* v2/tools/gcc.jam
(init): parse the new options and call the new rule.
(init-link-flags): new rule. Initialize flags based on linker type.
put back -minpure-text
* v2/test/conditionals.py
small modification to avoid empty binaries.
Patch from Andre Hentz.
[SVN r25764]
introduce separate <link-runtime> feature.
Allow to use the 'lib' rule to declare
libraries that should be searched for.
* builtin.jam: Remove 'shared' features. Introduce
'link' and 'link-runtime'.
(searched-lib-target): New class
(searched-lib-generator): New generator.
(lib-action): New class, derived from 'action'.
Handles instances of 'searched-lib-target' in sources.
Also, moves all libraries from sources to property value,
so that we can repeat them twice in command line.
(lib-generator): Generator which uses 'lib-action'.
* generators.jam: Allow empty list of sources everywhere.
* virtual-target.jam (file-target): Split into
'abstract-file-target' and 'file-target'.
(abstra
(action.actualize-sources): New rule. Allows to
handle the fact that some sources are special,
and should not become $(>) in action body.
