Cédric VINCENT 1c1b40c162 arm-semi: Provide access to CLI arguments passed through the "-append" option
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.

Peter Maydell 206ae74aea arm-semi.c: Use correct check for failure of do_brk()
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.

Wolfgang Schildbach 2e8785acc6 Fix commandline handling for ARM semihosted executables
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.

This fixes https://bugs.launchpad.net/qemu/+bug/673613 .
