On 10.6, the main executable does not show up at index 0, but appears
elsewhere in the list. Modules are now scanned to ensure that the
MH_EXECUTE one is first in the list. This means that ProcessReader is
now responsible for creating a MachOImageReader object for each module,
rather than having its callers perform that task.

exception handler ports.
task_t, thread_t, and exception_handler_t are typedefs for mach_port_t.
They are more descriptive than mach_port_t, and are already in use in
exc_server_variants.

This also puts kMachExceptionCodes into mach_extensions.h, because a
form of MACH_EXCEPTION_CODES that’s the right type
(exception_behavior_t) has now shown its use in more than one file.

MachOImageSymbolTableReader.
This results in a speed boost for MachOImageSymbolTableReader because
it’s able to read the entire string table in one operation, rather than
reading each string from the remote process individually. Copying is
also reduced. In a debug-mode build on my laptop, util_test
MachOImageReader.* has improved from ~1400ms to ~1000ms.

This is part of a family of classes whose chief entry point is
MachOImageReader. MachOImageReader depends on this class to read
segments, so this one is landing first. The bulk of this class will be
tested as part of MachOImageReader.
