SL-821: Try to add SecondLife.log file to Mac BugSplat crash report.

Introduce new header file llappviewermacosx-for-objc.h to publish for
llappdelegate-objc.mm and other Objective-C++ consumers the free functions in
llappviewermacosx.cpp they consume. These were never before declared in any
header file. Apparently, to date, we've been trusting to luck that
Objective-C++ will infer the correct signature from calls -- and that the
calls are correct with respect to the function definitions.  :-P

This gives us a place to introduce a new getLogFilePathname() function to
query LLDir. (We don't simply #include "lldir.h" because of the pervasive use
of BOOL in viewer headers; BOOL means something very different in Objective-C++.)

+ * @brief  llappviewermacosx.h publishes the C++ API for
+ *         llappviewermacosx.cpp, just as
+ *         llappviewermacosx-objc.h publishes the Objective-C++ API for
+ *         llappviewermacosx-objc.mm.
+ *
+ *         This header is intended to publish for Objective-C++ consumers a
+ *         subset of the C++ API presented by llappviewermacosx.cpp. It's a
+ *         subset because, if an Objective-C++ consumer were to #include
+ *         the full llappviewermacosx.h, we would almost surely run into
+ *         trouble due to the discrepancy between Objective-C++'s BOOL versus
+ *         classic Microsoft/Linden BOOL.
