Message: WT-2846 Fix bugs related to reconfiguring eviction settings. (#2973)

Fix bugs related to reconfiguring eviction settings.

The code to support reconfiguring eviction worker threads had
several bugs. Implemented an abstracted utility thread group API
and switch eviction workers over to using the new abstraction.

• Remove unused function from new thread group API.

• Commit auto-generated files.

• Be more careful cleaning up on error in thread group code.

• Fix uninitialized variable.

• Ensure thread group structures are cleared after destruction.

This is necessary since the structure is re-used for eviction workers
when recovery is run.

• Remove util and worker as notions from thread group as per review feedback.

Implement other feedback review as well.

• Fix a bug where application threads could attempt to help with eviction
  before the server is setup.

Happens if using a shared cache so the cache size starts out at 0.

• Remove util prefix from thread group functions.

• Add session name to thread group. Fix some comments and whitespace.

• Restore error return path.

Message: WT-2846 Fixes for new thread group code (#2985)

• It isn't safe to assert that a lock isn't held before acquiring it.

• Signal the eviction server to speed up connection close.
