Relocate bodies of DTrace probes to the statically-linked VM.
Due to various operating systems (in both the DTrace and SystemTap
worlds) not fully supporting DTrace probes (or SystemTap-compatibility
mode probes) in shared libraries, we relocate those probes to the
statically-linked virtual machine. This could be seen as pollution
of the pristine VM by a (yet) experimental feature. However:
1. This code can be eliminated completely by the C preprocessor.
2. Leaving the probes in the dyntrace NIF shared library simply
does not work correctly on too many platforms.
*Many* thanks to Macneil Shonle at Basho for assisting when my
RSI-injured fingers gave out.
Tested on:
* CentOS 5, SystemTap 1.3
* Solaris 10 (note)
* Solaris 11
* OpenIndiana 151
* SmartOS 20120809T221258Z
* FreeBSD 9.0-RELEASE (note)
I had hoped to be able to test CentOS 6 + SystemTap 1.7, but the
details of dealing with all dependencies for a 2.6.32-279.5.1.el6.x86_64
kernel are too time consuming right now.
(note: Solaris 10 and FreeBSD 9.0-RELEASE can take a long time to compile)
