Fix warning caused by saving a const string in a non-const pointer

Fix test failures caused by failure to commit the temporary refcount DB. Files need to be closed before renaming over them on Windows.

Improve error logging in win32 emu library. Consistently capture the last Windows error code in the global variable winerrno. Add logging macros that report the Windows error message for this error code.

Hopefully fix clang detection on Travis. Travis clang reports its version as "clang version 3.4 (tags/RELEASE_34/final)", unlike "Ubuntu clang version 3.3-5ubuntu4~precise1".

Catch setitimer() failure, throw exceptions with descriptive messages in Timer.cpp.

Show compiler version for clang compile flags debugging

Whitespace and semicolon-after-macro fixes.

Add missing timeouts to Archive reads. Allows Archive to be used safely on network streams.

Update Mailman links (diff)
