0ffd3fdae9 Add stddef.h for POSIX ssize_t 
Recent GCC versions / OS headers don't automatically provide ssize_t
anymore, leading to compiler errors.

c802ad3a1a Support creation of struct lists with size 0 
The case of creating capnp lists of size 0 didn't consider lists of
composite elements (structs), which requires the addition of list
element information.

This commit removes the case of size 0 when creating the list in order
to enable the creation of 0 sized lists of any element type (struct).

7b7346a73c lib: make buf arg const in write_fd pointer 
For capn_write_fd() the write() function would be ideal to pass as
write_fd, but write() has type ssize_t (*)(int, const void *, size_t),
whereas write_fd expects ssize_t (*)(int, void *, size_t). Passing
write() directly with GCC 5.4 causes a warning
-Wincompatible-pointer-types (on by default).

81352b068d Revert "lib: endianness: don't break strict-aliasing" 
This reverts commit 1afce9573a.

Turns out this is a misunderstanding of the C standard...  meh.

There is no point in having these functions be part of the public API.

33ae16bba8 lib: don't overrun buffer in capn_write_mem_packed 
Missing braces end up scaling the offset by * 4 ... which is actually a
stack/heap overflow.

1afce9573a lib: endianness: don't break strict-aliasing 
Strict aliasing prohibits writing to union members of one type, then
reading another type.  The read is undefined.  Use memcpy instead (which
compilers will hopefully optimize away...)

b3b83e0343 lib: make endian check more platform-friendly 
neither Windows nor OSX have endian.h

autoconf checking this makes things worse on Windows too, so let's just
try endian.h on "unix" systems.

27df3d6064 Align capn_segment to 64-bit boundaries on MSVC 
Unless capn_segment is defined with __declspec(align(64)),
check_segment_alignment fails to compile in x86 mode, as (sizeof(struct
capn_segment)&7) -> (44 & 7) evaluates to 4
Always compiles in x64 mode, as (sizeof(struct capn_segment)&7) -> (80 &
7) evaluates to 0

8f37e0f618 Define default value for char *e 
Visual studio's execution flow analysis insists that (e) could be
undefined. I don't see it, but this permits compilation.
