media: Declare wildcard fields const.

This is a source compatibility break from BeOS, but should not
be an ABI one (I checked, the symbols are identical.)

Also use "= {}" in the definitions of the fields. We use this
in plenty of places in the kernel, so it should be OK for GCC2.

BMediaNode: Handle port read syscall interrupts by retrying.

The syscall might be interrupted, especially in signal heavy

runs out. since the timeout is already absolute we don't need to adjust
anything.

Fixes that make Haiku build with gcc 4. Mainly out of the following
categories:
* Missing includes (like <stdlib.h> and <string.h>).
* Linking against $(TARGET_LIBSTDC++) instead of libstdc++.r4.so.
* Local variables shadowing parameters.
* Default parameters in function definitions (as opposed to function
declarations).
* All C++ stuff (nothrow, map, set, vector, min, max,...) must be imported
explicitly from the std:: namespace now.
* "new (sometype)[...]" must read "new sometype[...]", even if sometype is
something like "const char *".
* __FUNCTION__ is no longer a string literal (but a string expression), i.e.
'printf(__FUNCTION__ ": ...\n")' is invalid code.
* A type cast results in a non-lvalue. E.g. "(char *)buffer += bytes"
is an invalid expression.
* "friend class SomeClass" only works when SomeClass is known before.
Otherwise the an inner class with that name is considered as friend.
gcc 4 is much pickier about scopes.
* gcc 4 is generally stricter with respect to type conversions in C.
