exclude several boost libraries from build

[smanders]

boost libraries https://www.boost.org/doc/libs/

1. atomic - used in Vantage
   • should be removed?

     It implements the interface as defined by the C++11 standard, but makes this feature available for platforms lacking system/compiler support for this particular C++11 feature.

2. chrono - used in Vantage
3. container - used in Vantage
4. context
5. contract
6. coroutine/coroutine2
7. date_time - used in Vantage
8. exception - used in Vantage
9. fiber
10. filesystem - used in Vantage
11. graph - used in Vantage
12. graph_parallel
13. iostreams - used in Vantage
14. locale
    • currently doesn't build
15. log - used in mdp
16. math
    • currently doesn't build with clang
    • math/special_functions - used in Vantage
    • math/constants - used in Vantage
    • math/complex.hpp - used in mdp
17. mpi
    • currently doesn't build
18. program_options - used in Vantage
19. python
20. random - used in Vantage
21. regex - used in Vantage
22. serialization - used in ATT
23. signals - used in Vantage
24. stacktrace
25. system - used in Vantage
26. test - used in Vantage
27. thread - used in Vantage
28. timer - used in Vantage
29. type_erasure
30. wave

recommend removing from the default build:

1. context
2. contract
3. coroutine
4. fiber
5. graph_parallel
6. locale (already is)
7. math (check that nothing requires it)
8. mpi (already is)
9. python
10. serialization (why is ATT using it?)
11. stacktrace
12. type_erasure
13. wave

serialization... ATT should be using boost/optional.hpp not boost/serialization/optional.hpp (in two places)

removing libraries without dependencies

[smanders]

completed with commits to dev branch referenced above

with a pre-release version of externpro 18.08.1 and with the changes made to the boost use script I'm seeing link errors on every executable that links boost libraries

/opt/extern/externpro-18.08.1-gcc640-64-Linux/lib/libboost_prg_exec_monitor-gcc64-mt-s-1_63.a(cpp_main.o): In function `main':
cpp_main.cpp:(.text.startup+0x8): undefined reference to `cpp_main(int, char**)'
collect2: error: ld returned 1 exit status

since prg_exec_monitor was excluded from Boost_LIBS prior to these changes (see usexp-boost-config.cmake https://github.com/smanders/externpro/commit/41e103efae7d535156e020f4672046bf5ebce74f), I'm opting to remove it again

it appears the "program execution monitor" is a boost test library (I was only able to find reference to it in old boost docs https://www.boost.org/doc/libs/1_57_0/libs/test/doc/html/prg-exec-monitor.html)

a project (Vantage) that uses externpro (and boost) builds and links fine on linux with gcc, but fails on Windows with MSVC: LNK1104: cannot open file 'libboost_serialization-vc140-mt-s-1_63.lib'

of course boost serialization was one of the libraries excluded because it didn't appear that Vantage used it (outside of a couple of errant includes in Autotest code) -- this failure is quite early in the build (executables that link Sdimage and it's dependencies - MosaicIntegrationTest and SdimageTest)

searching the boost includes (grep -r "include <boost/serialization") it appears that there are other boost libraries (some header-only) included by Vantage that include serialization headers: graph, bimap, units, geometry, numeric

I'm not how to exactly determine which boost library (or something else?) is causing the linker to require boost serialization, but the way boost uses pragma comment lib to specify library dependencies (usually in a boost serialization header, which would make the library required if anything includes a boost serialization header) it's going to be easier to just include boost serialization in the externpro build of boost again...
