    Fix: tracepoint.h incorrect assumption about constructor order

    Incorrect assumption about constructor execution order can trigger a
    segfault when trying to execute tracepoint_register_lib.

    Fix: tracepoint instrumentation constructor order issue

    If the linker decides to run a constructor from a tracepoint probe
    before the constructor from the application, a recent modification
    (commit 558b9d86247004f8e9bbaf8c982f3b2b182093d1) allowed that the wrong
    constructor execution order could prohibit the program's tracepoints
    from being registered.

    Fix this by making two separate constructors.

    Fixes #487

    Fix: ensure all probe providers have their symbols

    Original commit log from stable-2.2:
    Following the removal of metadata generation from UST, the probes cannot
    find the tracepoint_dlopen() symbol. Ensure those probes can be built by
    declaring this symbol within each probe.

    stable-2.1 backport:
    Similar issue was experienced with the "demo" test program when built
    outside of the UST tree.
