Remove still-born a.out support. The BSDs switched from a.out to ELF 20+ years
ago. It's out of scope for bsd-user, and what little support there was would
simply wind up at a not-implemented message. Simplify the whole mess by removing
it entirely. Should future support be required, it would be better to start from
scratch.

Use the PATH to find the executable given a bare argument. We need to do
this so we can implement mixing native and emulated binaries (e.g.,
execing a x86 native binary from an emulated arm binary to optimize
parts of the build). By finding the binary, we will know how to exec it.

It was incorrect to subtract off the size of an unsigned int here.  In
bsd-user fork, this change was made when moving the arch specific items
to specific files.  The size in BSD that's available for the arguments
does not need a return address subtracted from it.

Pass the bsd_param into loader_exec, and adjust. We use it to track the
inital stack allocation and to set stack, open files, and other state
shared between bsdload.c and elfload.c

On OpenBSD the compiler complains:
bsd-user/bsdload.c:54:17: warning: variable 'id_change' set but not used [-Wunused-but-set-variable]

This is dead code that was originally copied from linux-user.
We fixed this in linux-user in commit 331c23b5 in 2011;
delete the useless code from bsd-user too.

This reverts commit 1fba5095.

That commit converted various fprintf(stderr, ...) calls to
use error_report(); however none of these bsd-user files include
a header which gives a prototype for error_report, so this
causes compiler warnings. Since these are just straightforward
reporting of command line errors, we should handle these in the
obvious way by printing to stderr, as we do for linux-user.
There's no need to drag in the error-handling framework for this,
especially since user-mode doesn't have the "maybe we need to
send this to the monitor" issues system emulation does.
