None of the code uses it any more. This means that `libsysprof-capture.a`
can now be used within `libglib-2.0.so` for collecting main loop
statistics.

Fixes: #40
This is a simplified API for the inferior to use (such as from a
LD_PRELOAD) that will use mmap()'d ring buffer created by Sysprof. Doing
so can reduce the amount of overhead in the inferior enough to make some
workloads useful. For example, collecting memory statistics and backtraces
is now fast enough to be useful.
This allows embedding the static capture library without having to deal
with license incompatibility while retaining the patent clause. We want
as many consumers of the format as makes sense without the restriction
of what kind of app/library/tooling they are.
The application, sysprofd, libsysprof, and libsysprof-ui continue to be
GPLv3+.
As we gain in usage, we need to be more careful about using a prefix
that will not collide with other symbols. So version 3 of our ABI will
change to using Sysprof/SYSPROF/sysprof as the various prefixes.
The soname/api version bump will happen later on this branch so that
things are easier to test up until then.
This moves everything into other places and simple includes the
files in the cases that it is necessary. In the future, we can
rewrite sysprofd to use GDBus and add GetProcFile() to allow
for client-side processing of kallsyms.
The big thing going on here is that we are going to split up the libraries
a bit better, and remove GObject from the capture library. The libsysprof
library will bring in the capture library statically, so we can export the
symbols we want.
Eventually, we will bump the version to sysprof-3, but not yet.
