Rather than requiring an explicit image_pecoff_parse, do it
unconditionally in image_load. We don't have any instances where we need
to do this separately.

Change image_write_signed to image_write, and conditionally write the
signature if one is present.
This will allow us to write unsigned images when detaching a sig from an
image.

Fix a few warnings:
idc.c: In function ‘IDC_get’:
idc.c:248:12: warning: ‘idclen’ may be used uninitialised in this function [-Wuninitialized]
image.c: In function ‘image_load’:
image.c:37:15: warning: unused variable ‘bytes_read’ [-Wunused-variable]
Plus, a bunch of strict-aliasing warnings:
image.c:101:2: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]
[ similar warnings trimmed ]
when compiling image.c. Since struct external_PEI_DOS_hdr uses char[]
types for all members, we need to use accessors here.

Add an option (--detached) to sbsign, which creates a detached
signature, rather than embedding it in the PE/COFF signature table.

GPLv3; the sources include parts of binutils, include parts of ccan,
and have been partially based of osslsigntool.
