Added Expat XML parser.

Usage:

hunter_add_package(EXPAT)

find_package(Expat REQUIRED)

add_executable(foo foo.c)
target_compile_definitions(foo PRIVATE XML_STATIC)
target_link_libraries(foo PRIVATE ${EXPAT_LIBRARIES})
target_include_directories(foo PRIVATE ${EXPAT_INCLUDE_DIRS})

I think it must be 'hunter_add_package(Expat)' here. Probably on OS like Mac or Windows it doesn't matter but on case sensitive platforms like Linux it will be an error.

Thanks. Fixed.

@alamaison Hi, Alex! I've fixed some issues with applying toolchain flags to C project (see details). Now some CI testing start failing at analyze toolchain (issue was that wrapper for clang analyzer was not used for C code but only for C++ code).

See Expat errors: https://travis-ci.org/ruslo/hunter/jobs/93227575#L606

I will disable it for now. Let me know if you want to fix it - I will enable it back after update.

Thanks, Ruslo

Sorry @ruslo, I've not had much free time lately. Will look at this if I get a chance, but it might not be soon :( Looks like issues in the upstream projects.
