This commit does the following things to fix compilation on FreeBSD:
1. Add required typedefs to linux/types-compat.h.
2. Remove unnecessary include linux/ioctl.h and replace linux/types.h
with linux/types-compat.h. Both files do not exist on FreeBSD.
3. Check the header including makedev macro. FreeBSD does not have
sys/sysmacros.h, and including it unconditionally causes error.

Most of the features we need are very early or not expose yet in the uAPI.
Using an internal copy ensure that we everything we need is defined avoiding
to add load of checks and conditionnal code.
