Remove unneeded include statements, remove conditional statements and
replace the remaining assert.h by their standard C++ variant cassert.

genericvector.h used a mix of assert and ASSERT_HOST.
By using assert only, it does no longer depend on errcode.h
which defines the ASSERT_HOST macro.
Other files which still use ASSERT_HOST now need an explicit
include statement for errcode.h.
