After recent changes of wxLogXXX() functions into macros the last error was
overwritten by wxString::Format() called between the call to wxLogSysError()
and wxLog::CallDoLogNow() which called wxSysErrorCode() and so its original
value was lost and, unless the last error was specified explicitly, it always
came out as 0.
To fix this, call wxSysErrorCode() directly when calling wxLogSysError(). This
may be unnecessary (if the error is given explicitly) but there doesn't seem
to be any other way to fix it and the overhead of calling wxSysErrorCode()
shouldn't be that big.
Also add a unit test checking that wxLogSysError() behaves as expected.

Each log message is now associated with its component, "wx" by default for
messages generated by wxWidgets and wxLOG_COMPONENT in general (which is empty
by default). Each component may have its own log level and they are
hierarchical allowing fine configuration of what exactly is logged.

The main logging callback is now DoLogRecord() with DoLogTextAtLevel() and
DoLogText() provided for convenience. The old DoLog() and DoLogString() are
still called but deprecated and their overloads taking wxString which were
only added in 2.9.0 are removed.
wxLogRecordInfo allows associating more information than just the time stamp
with the log record; for now only the logging thread id was added but more
fields will make their appearance soon.
