The stream handler assumed all HTTP headers contained exactly one space,
but the standard says there may be zero or more. Should fix Bug #47021,
and any other edge cases caused by a web server sending unusual spacing,
e.g. the MIME type discovered from Content-Type: can no longer contain
leading whitespace.
We strip trailing whitespace from the headers added into
$http_response_header as well.

Avoid many string duplications, use interning (browscap-local, of
course), reduce pattern size, use more compact key-value
representation, build result array only on demand.
Testing corpus provided by Anatol against current browscap.ini lite.
About 30% of all agents are not recognized by this browscap.ini,
but this should give us decent coverage.
Particularly on slower VMs, the sporadic fails can still happen.
The timing is kept in an uncritical range, but allows the tests
pass there. Mayby, it'd make sense to introduce a new group for
this kind of tests, so tests requiring exact time measurement
can be avoided on unsuitable environments.
Simplify some unnecessarily complicated code. In particular the
length updates are unnecessary (length is only used at the very
start) and we're goto'ing around a bit too much.
The E_WARNING message from the PHP function lchown is passed
from the system function lchown. The error message returned
from lchown can be filesystem dependent.
