29718712eb bsd-user: Fix possible memory leaks and wrong realloc call
These errors were reported by cppcheck:

[bsd-user/elfload.c:1108]: (error) Common realloc mistake: "syms" nulled but not freed upon failure
[bsd-user/elfload.c:1076]: (error) Memory leak: s
[bsd-user/elfload.c:1079]: (error) Memory leak: syms

v2:
* The previous fix for memory leaks was incomplete (thanks to Peter Maydell for te hint).
* Fix wrong realloc usage, too.

67af42ac5a Remove dead code for ARM semihosting commandline handling
There are some bits in the code which were used to store the commandline for
the semihosting call. These bits are now write-only and can be removed.

f66724c99a Add new user mode option -ignore-environment
An empty environment is sometimes useful in user mode.
The new option provides it for linux-user and bsd-user
(darwin-user still has no environment related options).

The patch also adds the documentation for other
environment related options.

e5924d8980 Replace most gcc format attributes by macro GCC_FMT_ATTR (format checking)
Since version 4.4.x, gcc supports additional format attributes.
    __attribute__ ((format (gnu_printf, 1, 2)))
should be used instead of
    __attribute__ ((format (printf, 1, 2))
because QEMU always uses standard format strings (even with mingw32).

The patch replaces format attribute printf / __printf__ by macro
GCC_FMT_ATTR which uses gnu_printf if supported.

It also removes an #ifdef __GNUC__ (not needed any longer).
