7d4f187700 clang: Enable compiling gem5 using clang 2.9 and 3.0
This patch adds the necessary flags to the SConstruct and SConscript
files for compiling using clang 2.9 and later (on Ubuntu et al and OSX
XCode 4.2), and also cleans up a bunch of compiler warnings found by
clang. Most of the warnings are related to hidden virtual functions,
comparisons with unsigneds >= 0, and if-statements with empty
bodies. A number of mismatches between struct and class are also
fixed. clang 2.8 is not working as it has problems with class names
that occur in multiple namespaces (e.g. Statistics in
kernel_stats.hh).

clang has a bug (http://llvm.org/bugs/show_bug.cgi?id=7247) which
causes confusion between the container std::set and the function
Packet::set, and this is currently addressed by not including the
entire namespace std, but rather selecting e.g. "using std::vector" in
the appropriate places.

c2dbfc1d6c MAC: Make gem5 compile and run on MacOSX 10.7.2
Adaptations to make gem5 compile and run on OSX 10.7.2, with a stock
gcc 4.2.1 and the remaining dependencies from macports, i.e. python
2.7,.2 swig 2.0.4, mercurial 2.0. The changes include an adaptation of
the SConstruct to handle non-library linker flags, and Darwin-specific
code to find the memory usage of gem5. A number of Ruby files relied
on ambigious uint (without the 32 suffix) which caused compilation
errors.

7bc68151b7 LibElf: Build the error management code in libelf.
This change makes some minor changes to get the error management code in
libelf to build on Linux and to build it into the library.

05d8c9acb8 scons: Rename the basic environment from env -> main.
env is used as a local variable all over the place and sometimes it is
easy to get confused as to whether the global env or local env is being
used.  This will become especially important when I change the way we
support our variants.

56e5509bfd scons: Fix two problems with the way that the library path is generated.
1) -L is automatically added, so don't do it ourselves
2) prepend the paths for gzstream and libelf so they are certain to
come first. The problem is that python might add /usr/lib to the path
and the user might have a locally installed version of libelf installed.

dd6ea8797f scons: Require SCons version 0.98.1
This allows me to clean things up so we are up to date with respect to
deprecated features.  There are many features scheduled for permanent failure
in scons 2.0 and 0.98.1 provides the most compatability for that.  It
also paves the way for some nice new features that I will add soon

a589eb4053 SCons: add code to provide a libm5 shared library.
Targets look like libm5_debug.so.  This target can be dynamically
linked into another C++ program and provide just about all of the M5
features.  Additionally, this library is a standalone module that can
be imported into python with an "import libm5_debug" type command
line.

    pull in the CC/CXX variables from env. Use gm4 if it exists
ext/libelf/elf_begin.c:
ext/libelf/libelf_allocate.c:
    include errno.h instead of sys/errno.h
ext/libelf/elf_common.h:
    use the more standard uintX_t
ext/libelf/elf_strptr.c:
