compositor-drm: Create header for backend internals
Create a new header called drm-internal.h, and move many of drm.c's declarations and helpers to it. This will allow us to split the DRM backend into multiple files. Signed-off-by: Daniel Stone <daniels@collabora.com>

* - fixed uint32_t values, including Weston object IDs such as weston_output
|
||||
* IDs, DRM object IDs such as CRTCs or properties, and GBM/DRM formats:
|

* "%lu (0x%lx)" (unsigned long) value, (unsigned long) value
|

*
|

* - fixed uint64_t values, such as DRM property values (including object IDs

* when used as a value):
|
||||
* "%llu (0x%llx)" (unsigned long long) value, (unsigned long long) value
|

*
|

* you want).
|

*
|

* This is to avoid implicit widening or narrowing when we use fixed-size
|

* types: uint32_t can be resolved by either unsigned int or unsigned long
|

* on a 32-bit system but only unsigned int on a 64-bit system, with uint64_t

* being unsigned long long on a 32-bit system and unsigned long on a 64-bit

* system. To avoid confusing side effects, we explicitly cast to the widest
