include/perf/evsel.h
which will be included by users.
The definitions are added into:
include/internal/evlist.h
include/internal/evsel.h
which is not to be included by users, but shared

Add perf_thread_map struct to libperf.
It's added as a declaration into into:
include/perf/threadmap.h
which will be included by users.
The perf_thread_map struct definition is added into:
include/internal/threadmap.h
which is not to be included by users, but shared within perf and
libperf.
We tried the total separation of the perf_thread_map struct in libperf,
but it lead to complications and much bigger changes in perf code, so we
decided to share the declaration.

Add a shared library version, generating the following files:
$ ll tools/perf/lib/libperf.so*
libperf.so -> libperf.so.0.0.1
libperf.so.0 -> libperf.so.0.0.1
libperf.so.0.0.1
Committer testing:
One has to build just libbperf to get this, building perf so far doesn't
trigger this, i.e. I tried:
$ make O=/tmp/build/perf -C tools/perf
And the files above were not created, so one has to do:
$ make O=/tmp/build/perf -C tools/perf/lib/
make: Entering directory '/home/acme/git/perf/tools/perf/lib'
LINK /tmp/build/perf/libperf.so.0.0.1
make: Leaving directory '/home/acme/git/perf/tools/perf/lib'
$ ls -la /tmp/build/perf/*.so.*

LINK libperf.so

Committer notes:
Need to add -I$(srctree)/tools/arch/$(ARCH)/include/uapi
-I$(srctree)/tools/include/uapi to tools/perf/lib/Makefile's INCLUDE
variable to pick up the latest versions of kernel headers, even in older
systems, this is in line with what is in tools/lib/bpf/Makefile.
