Nathan Hjelm 4d92c9989e more c99 updates
This commit does two things. It removes checks for C99 required
headers (stdlib.h, string.h, signal.h, etc). Additionally it removes
definitions for required C99 types (intptr_t, int64_t, int32_t, etc).

/* Update log
*
* Jul 12 2001 FNW: Add a meaningful ID to the communicator name, and switch
* to using the recv_context as the unique_id field.
* Mar 6 2001 JHC: Add mqs_get_comm_group to allow a debugger to acquire
* processes less eagerly.
* Dec 13 2000 JHC: totalview/2514: Modify image_has_queues to return
* a silent FALSE if none of the expected data is
* present. This way you won't get complaints when
* you try this on non MPICH processes.
* Sep 8 2000 JVD: #include <string.h> to silence Linux Alpha compiler warnings.
* Mar 21 2000 JHC: Add the new entrypoint mqs_dll_taddr_width
* Nov 26 1998 JHC: Fix the problem that we weren't handling
* MPIR_Ignore_queues properly.
* Oct 22 1998 JHC: Fix a zero allocation problem
* Aug 19 1998 JHC: Fix some problems in our use of target_to_host on
* big endian machines.
* May 28 1998 JHC: Use the extra information we can return to say
* explicitly that sends are only showing non-blocking ops
* May 19 1998 JHC: Changed the names of the structs and added casts
* where needed to reflect the change to the way we handle
* type safety across the interface.
* Oct 27 1997 JHC: Created by exploding db_message_state_mpich.cxx

/* Notice to developers!!!!
* The following include files with _dbg.h suffixes contains definitions
* that are shared between the debuggger plugins and the OMPI code base.
* This is done instead of including the non-_dbg suffixed files because
* of the different way compilers may handle extern definitions. The
* particular case that is causing problems is when there is an extern
* variable or function that is accessed in a static inline function.
* For example, here is the code we often see in a header file.
*
* extern int request_complete;
* static inline check_request(void) {
* request_complete = 1;
* }
*
* If this code exists in a header file and gets included in a source
* file, then some compilers expect to have request_complete defined
* somewhere even if request_complete is never referenced and
* check_request is never called. Other compilers do not need them defined
* if they are never referenced in the source file.
*
* In the case of extern functions we something like the following:
*
* extern int foo();
* static inline bar(void) {
* foo();
* }
*
* If this code exists it actually compiles fine however an undefined symbol
* is kept for foo() and in the case of some tools that load in plugins with
* RTLD_NOW this undefined symbol causes the dlopen to fail since we do not
* have (nor really need) the supporting library containing foo().
*
* Therefore, to handle cases like the above with compilers that require the
* symbols (like Sun Studio) instead of pulling in all of OMPI into the
* plugins or defining dummy symbols here we separate the definitions used by
* both sets of code into the _dbg.h files.
*
* This means if one needs to add another definition that the plugins must see
* one should either move the definition into one of the existing _dbg.h file or
* create a new _dbg.h file.
