Eliminates stall from saveObjectCache() on region deletion

SL-13540: Do not fail if binary bucket is too large, attempt to extract the asset type from the old style bucket. Notification still not shown.

The llappviewerwin32.cpp create_console() function called by
LLAppViewerWin32::initConsole() used to assign *stderr = *(new FILE* value),
and so forth for stdout and stdin. That dubious tactic no longer works with
the new Windows CRT introduced with VS 2015. freopen_s() works much better.

(cherry picked from commit 0b61150e)

There are separate stanzas in llappviewerwin32.cpp's create_console() function
for each of STD_INPUT_HANDLE, STD_OUTPUT_HANDLE and STD_ERROR_HANDLE. SL-13361
wants to add more code to each. Factor out new local set_stream() function and
make create_console() call it three times.

(cherry picked from commit 13b78a0c)

SL-11430, SL-9756: Take transaction-id from offline messages.  Correct LLSD names. Use offline flag rather than implicit tests of session_id and aux_id.
