Use getpid instead of GetCurrentProcessId as the latter calls into io-layer which is not initialzed at this point.
Take shared file lock before collecting file share_info.
Support for video/mp4, video/ogg, video/webm

Added support for the three leading HTML5 Video mime types
.mp4 video/mp4
.ogv video/ogg
.webm video/webm

When Internet Explorer 10 or 11 receives application/octet-stream as the mime type for HTML5 video, it will not play the video. This resolves the issue in an Apache/mod_mono environment.
Support for audio/ogg and audio/mp4

.ogg, .oga audio/ogg
.mp4a, .aac audio/mp4
http://tools.ietf.org/html/rfc4337

Added "m4a" for "audio/mp4" and "m4v" for "video/mp4"

http://tools.ietf.org/html/rfc5334#section-10.1

[MSBuild] Fixed a test that failed when the GAC wasn't available

The test tried to resolve an assembly from the GAC, which doesn't work on a
clean machine without an existing Mono installation.
We now check if the GAC directory is missing and ignore the test in that case.
[docs] Fixed XML syntax issue with CipherSuitsCallback, and ServicePointManager xml files.
[interpreter] Disable fast call invocation using methodinfo delegates due to aot limitation. Fixes #18688

[system.net.http] Close service-point slot on explicit dispose. Fixes #18848
[System.Core] Don't auto increment when trimming hashset. Fixes #18687
Revert "[runtime] Improve the hashing of MONO_TYPE_VAR/MONO_TYPE_MVAR. Hopefully fixes #18880."

This reverts commit 078dc0321d53f9e161957656550fd10cc41db618.

It's breaking for everyone.
Adjust scrollbar display after layout if autosized children

ScrollableControl.OnLayout sets the scroll bar display before doing the
actual layout.  If any children are autosized, they may change size as
a result of the layout, and that may change whether or not the scrollbar
is needed.  (This addresses Xamarin bug 18874.)
Fix assertion in test-mono-linked-list-set

When running 'make check', test-mono-linked-list-set fails with:

* Assertion at hazard-pointer.c:353, condition `small_id == i' not met

This happens since 71ad74dc11c5fa4bc8c178a5457d2cab732fdb01, because
that commit changes the behaviour of mono_thread_smr_init() so that
invoking it should not be invoked more than once.
