affect the names of the generated targets and only usefull for preventing
V2 from treating two independent targets as target alternatives.

The issue is that when with new response files the names of libraries we're
trying to link to is not emitted with "bjam -n", so remove "-n" and explicitly
look in response files.

There were two problems:
- 'glob' was using __name__ as the name of the project and not
project.current, so it would search in project root, and not in child
project that inherited project root rules.
- the 'import' that's overrided in project context used __name__ to
restore the value of current project
Thanks to Emil Dotchevski for the bug report.

* If a generator was given a source it could not handle, it used to return
that source together with generated targets. This was nice for some use
cases, but no very nice for others, and this behaviour could not be turned
off. One use case where it worked bad was:
lib plugin : plugin.cpp helper ;
lib helper : helper.cpp ;
On windows, 'plugin' would link to the 'import library' and pass the DLL
target though. So, when installing 'plugin', we'd also install 'helper.dll',
and it was not possible to do anything about it.
* If we asked generators.construct to produce sources of type CPP,
and the selected generator produced both targets of type CPP, and of
some other type, we'd try again to convert those other targets to CPP.
This simply complicated the logic for no good reason.
* Most generator function had 'multiple' parameter, which function
was long forgotten by anybody.
As a bit of history, I believe some of the above decisions were due to a
certain use case:
CPP <------- WHL
\
WD
/
CPP <------- DLP
Here, a source file is converted to two targets with one command, and each
produced file is converted to CPP. Our generators search would notice that
there are two generators for CPP: the WHL->CPP and DPL->CPP
generators. Neither is better that the other so both are tried, and produce
(CPP, DPL) and (CPP, WHL) pairs of targets. To avoid reporting an ambiguity,
we'd try to convert, DLP to CPP and WHL to CPP, do it successfully, notice
that produced targets are the same and decide that there's no ambiguity.
However, this is rather complex logic for a relatively rare case. It can
be handled by writing another WD->CPP generator that would handle
disambiguation itself.
This commit has one user-visible change. The code:
exe a : a.cpp b ;
obj b : b.cpp helper;
lib helper ;
No longer works -- the 'a' target won't link to 'helper'. However, this is
pretty stange code and worked before almost by accident.

The problem with the previous implementation is that it would iterate
over all elements in a dir even if 'pattern' had no metacharacters. First,
that was slow -- if you handed
/cygdrive/w/My Documents/boost/test/a.cpp
to it, it would crawl all the way to the top, listing each directory and
checking each file. Second, it would fail, because Cygwin is broken and
does not show 'cygdrive' is the list of directory elements of '/'.
Now we check if a pattern has metacharacters, and if not, just do
a simple 'timestamp' call.
The new glob is implemented as new 'GLOB-RECURSIVELY' builtin. I've decided
to use builtin since otherwise, we'd need 'does this name exist' builtin,
and if we need new builtin, why don't implement all globbing in core.
