      lib: convert to HM diagnostic messages · 3fef97c6
      Philippe Gerum authored 
      

Since ABI 23, the core is able to channel T_WOSS, T_WOLI and T_WOSX
error notifications through the offender's observable component if
present.

Convert all SIGDEBUG_xxx cause codes to the new EVL_HMDIAG_xxx naming,
so that we have a single nomenclature for these errors regardless of
whether threads are notified via SIGDEBUG or their observable
component.

The API rev. is bumped to #17 as a result of these changes.

      lib: introduce the interface to observables · f27fc993
      Philippe Gerum authored 
      

Since ABI 23, the core provides the new observable element, which
enables the observer design pattern. Any EVL thread is in and of
itself an observable which can be monitored for events too.

As a by-product, the poll interface can now be given a user-defined
opaque data when subscribing file descriptors to poll elements, which
the core passes back on return to evl_poll().

      lib: introduce element visibility attribute · 9b42b85e
      Philippe Gerum authored 
      

Since core ABI 21, users can decide whether a new element should be
made public or private depending on the value of clone flags added to
the new long form of all element creation calls, i.e. evl_create_*().
All evl_new_*() calls become a shorthand for their respective long
form with reasonable default arguments, including private visibility.

As a shorthand, libevl also interprets a slash character leading the
name argument passed to these services as an implicit request for
creating a public element. In other words, this is the same as passing
EVL_CLONE_PUBLIC in the clone flags.

A public element appears as a cdev in the /dev/evl hierarchy, which
means that it is visible to other processes, which may share it. On
the contrary, a private element is only known from the process
creating it, although it does appear in the /sysfs hierarchy
regardless.

e.g.:

efd = evl_attach_self("/visible-thread");

crw-rw----    1 root     root      248,   1 Apr 17 11:59 clone
crw-rw----    1 root     root      246,   0 Apr 17 11:59 visible-thread

or,

efd = evl_attach_self("private-thread");

total 0
crw-rw----    1 root     root      248,   1 Apr 17 11:59 clone
