This change brings up the support of context-sensitive profiles in the format of extended bianry. Existing sample profile reader/writer/merger code is being tweaked to reflect the fact of bracketed input contexts, like (`[...]`). The paired brackets are also needed in extbinary profiles because we don't yet have an otherwise good way to tell context apart from regular function names. The context delimintor `@` can somehow serve as a part of the C++ mangled names.
