    Bugzilla 14672

    Added namespace file ("ns-{namespace}.xml") summary and remarks into the nsSummaries, which results in displaying the data prior to the namespace type-list when the user searches at the namespace level.

    Appears to only be necessary for native viewer (Web viewer for some reason "knows" about the summaries).
[runtime] Avoid looking up pinvoke addresses when AOT compiling.
[runtime] Add support for constrained gsharedvt calls to normal virtual methods.
[runtime] Add Steve Reid's public domain SHA1 code.
Resurrect the AOT cache code. Rename the env variable to MONO_AOT_ON_DEMAND. Add support for
multiple configurations for the same assembly. AOT in a forked process instead of
spawning a new runtime executable.
