errno feature branch

[Gregory Nutt <sp...@gmail.com>]

FYI..

I have just create a branch called 'errno' in both incubator_nuttx and 
incubator_nuttx_apps.  This is where we will be implementing new errno 
support as documented in Issue #986 "Userspace errno" 
(https://github.com/apache/incubator-nuttx/issues/986)

The implementation is not so complex that it requires a feature branch.  
However, there is some risk in changing the errno implementation so it 
is best that we test all that we can on a feature branch before merging 
to master.

There are several features described in the referenced Issue 986.  Only 
the the TLS errno has been implemented.  That logic has passed all of 
the PR checks, and tests on several platforms (still testing).  It has 
been merged to master.  If you see any unusual behaviors, please let us 
know ASAP.

The errno feature branch is gone for now, but will probably come back 
when we begin implementing the other features of issue 986
