c99: remove vim_round #909

C89 did not have round(), vim emulated it with vim_round. But since we're
using C99 this is not a problem anymore.
vim-patch:7.4.291 #879

Problem:    Compiler warning for int to pointer of different size when DEBUG
            is defined.
Solution:   use smsg() instead of EMSG3().

Include stdbool.h in some files which use it

Done by manual inspection of the output of this script:
grep -r -l -w "bool\|true\|false" * | grep 'c$\|h$' > has_bool
grep -r -l "stdbool.h" * | grep 'c$\|h$' > has_include
grep -F -x -v -f has_include has_bool
Remove stdbool.h from files which don't need it

Done by manual inspection of the output of this script:
grep -r -l -w "bool\|true\|false" * | grep 'c$\|h$' > has_bool
grep -r -l "stdbool.h" * | grep 'c$\|h$' > has_include
grep -F -x -v -f has_bool has_include
Include stdbool.h in headers which have functions with bool in signature

Done by manual inspecting of the output of this script:
grep -r -l -w "bool" * | grep 'c$' | sed 's/.c$//' > has_bool
grep -r -l -w "stdbool.h" * | grep 'h$' | sed 's/.h$//' > has_include
grep -F -x -v -f has_include has_bool

Refactor the lua dependency checking.

This is in preparation for the next step, which is to find a suitable
lua interpreter, rather than just erroring when an interpreter is found
but doesn't have the necessary dependencies.

Check dependencies for each lua interpreter.

- When USE_BUNDLED=OFF and the system has multiple lua interpreters
  (luajit AND lua) it may occur that only the later has the needed
  dependencies (lua-lpeg, lua-cmsgpack). If we pick luajit then
  finding the dependencies FAILS.
- This commit groups detection of the lua interpreter with the lua
  dependencies it tries to find them for both the interpreters and
  choses the first one that has them.
