New description:

 The following is a draft of the edits a set of new APIs are coming to
 POSIX.

 https://www.opengroup.org/austin/docs/austin_1110.pdf

 Search for "+" for added lines. Some are text changes and others are API
 additions. Some like strlcat() have been around for ages. Others are new
 like pthread_cond_clockwait() and similar "clockwait" methods for many
 (all?) concurrency primitives.

 This ticket is to perform the analysis to identify the list of methods and
 constants that are added, determine if RTEMS/newlib/libbsd currently
 supports that, and file tickets as appropriate to add them to the RTEMS
 environment.

 The analysis can be done as part of a GSoC project proposal effort. The
 GSoC project itself would consist of adding missing methods. There appear
 to be groups of related methods and the resulting tickets should reflect
 what would be added as a set.

 I have not and likely will not soon make it through this document to make
 a list of the new APIs. This list would then need to be checked against
 RTEMS and newlib. It is clear we are missing an entire class of new
 concurrency methods.
