Avoid C-style cast warnings
hardware/libhardware/include was being included with -isystem, which
hides warnings. Use a macro to convert modules to hw_device_t** to call
the open function that works in C++ and C.

Described restrictions for common HAL object methods.
Inheritance of HAL object is performed by composing a child structure of a
single parent structure located at offset 0 followed by new data members
and function pointers in the child structure.
For example,
struct child {
struct parent common;
int a_data_member;
void (*a_method)(struct child *c, int v);
};
HAL code assumes this layout when accessing child structures given a pointer
to a parent structure such that users write code like the following...
void child_method(struct *parent, int v) {
struct child * c = (struct child*)parent;
// do stuff with c
}
Code above will break if a member is added before "common" in "struct child".
This change adds comments that describe the restriction on the location of
parent HAL objects within a derived HAL object. HAL objects that already
have comments that describe the required location of parent objects are not
modified.

split fb.h out of gralloc.h
fb and gralloc are part of the same HAL for now,
but for clarity we split them into these two headers.
