Replace INT32 with a new internal datatype (JLONG)

Browse Source 
These days, INT32 is a commonly-defined datatype in system headers.  We
cannot eliminate the definition of that datatype from jmorecfg.h, since
the INT32 typedef has technically been part of the libjpeg API since
version 5 (1994.)  However, using INT32 internally is risky, because the
inclusion of a particular header (Xmd.h, for instance) could change the
definition of INT32 from long to int on 64-bit platforms and thus change
the internal behavior of libjpeg-turbo in unexpected ways (for instance,
failing to correctly set __INT32_IS_ACTUALLY_LONG to match the INT32
typedef-- perhaps as a result of including the wrong version of
jpeglib.h-- could cause libjpeg-turbo to produce incorrect results.)

The library has always been built in environments in which INT32 is
effectively long (on Windows, long is always 32-bit, so effectively it's
the same as int), so it makes sense to turn INT32 into an explicitly
long datatype.  This ensures that libjpeg-turbo will always behave
consistently, regardless of the headers included at compile time.

Addresses a concern expressed in #26.

*
* NOTE: The INT32 typedef dates back to libjpeg v5 (1994.) Integers were
* sometimes 16-bit back then (MS-DOS), which is why INT32 is typedef'd to
* long. It also wasn't common (or at least as common) in 1994 for INT32 to be
* defined by platform headers. Since then, however, INT32 is defined in
* several other common places:
*
* Xmd.h (X11 header) typedefs INT32 to int on 64-bit platforms and long on
* 32-bit platforms (i.e always a 32-bit signed type.)
*
* basetsd.h (Win32 header) typedefs INT32 to int (always a 32-bit signed type
* on modern platforms.)
*
* qglobal.h (Qt header) typedefs INT32 to int (always a 32-bit signed type on
* modern platforms.)
*
* This is a recipe for conflict, since "long" and "int" aren't always
* compatible types. Since the definition of INT32 has technically been part
* of the libjpeg API for more than 20 years, we can't remove it, but we do not
* use it internally any longer. We instead define a separate type (JLONG)
* for internal use, which ensures that internal behavior will always be the
* same regardless of any external headers that may be included.
