FindBoost.cmake from upstream cmake now finds python libraries like
find_package(Boost 1.67 python36)
and it export targets like Boost::python36
but we are still linking against Boost::python, so to be compatible
with FindBoost.cmake, we need to update BuildBoost.cmake and
mgr/CMakeLists.txt accordingly. in other words, to export
Boost::python36 and to link Boost::python36.

we have 'DH_VERBOSE=1' in debian/rules, which instructs debhelper to
pass -DCMAKE_VERBOSE_MAKEFILE=ON to cmake. but the verbose output for
building boost does not really help if something goes wrong while
building the deb packages. if we do want to enable the verbose output,
we can always enable it by passing `-d <N>' to it. see
https://boostorg.github.io/build/manual/develop/index.html#bbv2.overview.invocation.options

the new behavior of get_target_property(<var> <target> SOURCES) will be
enforced in future versions of cmake, so let ready for this change now
by removing the generator expressions from the returned source file
list.

* to pick up the fix of https://svn.boost.org/trac10/ticket/11622
* also the boost::python's library name now includes the version suffix
of python version, so update BuildBoost.cmake accordingly.

because FindBoost.cmake defines Boost::boost as the target for header
only dependencies.
due to the limit of cmake < 3.1, this only applies to cmake > 3.1

so the dependencies can be included when linking against the one which
depends on them. for example, libboost_filesystem depends on
libboost_system, if we don't link against the latter, linker will bail
out when linking an executable using Boost::filesystem.

the boost override for add_library() does not work for ALIAS targets:
CMake Error at cmake/modules/BuildBoost.cmake:227 (add_dependencies):
Cannot add target-level dependencies to alias target "Seastar::seastar".

after bumping up the required boost version, old copy of boost in
src/boost will not work. so we need to error out early.

* user-config.jam is the suggested way for adding toolset for Boost.Build.
* always specify toolset when running b2, so we can build boost with
specified compiler instead of the default one guessed by boost building system.

config.hpp does not exist if boost is not configured. so a boost source
directory unpacked from dist tarball does not have this file. the
bootstrap.sh instead, it is used to create the necessary config files
for jam.
