This patch basically adapts the new semi-hosting command-line support
-- introduced by Wolfgang Schildbach in the commit 2e8785ac -- for use
in system-mode.
Note that the "arm_cmdline_len" and "host_cmdline_len" variables were
renamed respectively "input_size" and "output_size" because:
* in C, the term "length" is generally used to count the number of
character in a string, not to count the number of bytes in a
buffer (as it is the case here).
* in QEMU, the term "host" is used to name variables that are in
the host address space, not to name variables in the target
address space (as it is the case here).
* in the case of this system-call, the terms "input" and "output"
fit the semantic of the official ARM semi-hosting specification
quite well.
I know renaming can be considered harmful but I do think in this case
the semantic really matters to keep this code more understandable.

In the ARM semihosting implementation of SYS_HEAPINFO, use the correct
check for whether do_brk() has failed -- it does not return -1 but the
previous value of the break limit.

Use the copy of the command line that loader_build_argptr() sets up in guest
memory as the command line to return from the ARM SYS_GET_CMDLINE semihosting
call. Previously we were using a pointer to memory which had already been
freed before the guest program started.
