 Description   

mongo::Mutex currently has a single mongo::LockActions smart pointer without an onLock() function. We should expand mongo::Mutex to keep a linked list and mongo::LockActions to have a full suite of hooks. In addition, all LockActions hooks should probably pass a const mongo::Mutex pointer.

Message: SERVER-41357 SERVER-41360 SERVER-43324 Add Mutex, BasicLockableAdaptor, and DiagnosticInfo

This commit backports Mutex, BasicLockableAdaptor, and DiagnosticInfo to
v4.2. These pieces came in completely in various interleaved commits.
The constituent commits partially included in this backport are listed
below. The majority of these commits are part of the "Improved
Diagnostics for Latches" epic.

Mutex:

BasicLockableAdaptor:

DiagnosticInfo:

Note that while this commit adds these pieces and integrates them into
the mongo-server codebase, it does not convert existing stdx::mutex
construction. It also does not include the updates to Interruptible that
were done as part of "Improved Diagnostics for Latches".
Branch: v4.2
