netinet/in: Use the GCC4 builtin byteswap functions for htonl.

Fixes the build breakage caused by PulkoMandy's recent commit.
Remove these from ByteOrder.h now also, as per POSIX they should
come from netinet/in.h.

This is a small source compatibility breakage, but it will only
affect a small portion of non-POSIX, partially-Be applications.

ByteOrder.h: add explicit casts when using gcc builtins

Those return uintNN_t types instead of our own types,
but uint32 for example is long while uint32_t isn't,
giving some trouble with the PRI* macros for example on PPC.

Style fixes to Support Kit files

Revert "ByteOrder.h: remove use of __builtin_bswap16."

This reverts commit 040dc2eebc6628cc05c4ac5e287c5287c5dacf2e.

ByteOrder.h: remove use of __builtin_bswap16.

* Fixes the build for host compilers older than gcc-4.8

ByteOrder.h: simplify compiler test

* A problem with our gcc requires adding casts for gcc4 when
the __builtin_bswap functions are used with a format string
* Unlike gcc2, the __builtin_bswap functions do not get disabled
despite using -fno-builtins, hence added compiler check in
runtime_loader/utility.cpp

Use GCC builtins for byte-swapping. Fixes #10800.

* Introduced in gcc-4.3 for at least Intel platforms
* On ARM, full support added in gcc-4.8
* Other platforms untested, left as-is
* This introduces a breaking change to the ABI for gcc4

Patch by Scott:
Make sure the comments are C style in headers that are included by POSIX
headers.

Thanks! Should fix #2870.

* Rewrote headers as necessary; only Errors.h and Debug.h still originate from a Be header now;
feel free to change that ;-)
* Cleaned up existing headers.
* Coding style guide update to BBufferIO (renamed m_* members to f*).

It is accomplished ...
