Solaris requires endian macros in liblwgeom for lwin_wkb and lwout_wkb

[rroliver]

Also refer to #473 #365 #623

Endian macros BIG_ENDIAN, LITTLE_ENDIAN and BYTE_ORDER are not provided by solaris.

By default _BIG_ENDIAN or _LITTLE_ENDIAN will be defined depending on the given target system

Find attached a patch which a) Moves inclusion of <sys/param.h> (for mingw etc. see #473) into

liblwgeom_internal.h from lwin_wkb.c and lwout_wkb.c

b) defines LITTLE_ENDIAN and BIG_ENDIAN if still undefined c) If BYTE_ORDER undefined, defines it appropriately on solaris (though does

not catch for other OSes if BYTE_ORDER undefined...)

Not sure which other OSes do not define the above.

Also not sure if this should really go into a separate header (lw_endian.h ?) that is included by liblwgeom_internal.h

Thoughts?

First cut at adding endian macros for solaris

[strk]

I think we should internally use: ./liblwgeom/liblwgeom_internal.h:extern char getMachineEndian(void);

[strk]

I'll work on it, get ready for testing.

Please try r8488 and let me know. Thank you.

BYTE_ORDER now passes properly, next missing on Solaris is the definition of INFINITY for postgis/gserialized_gist_2d.c - I think that's the last one. Shall we keep this as a general Solaris ticket ?

[strk]

No please, file a new one. Possibly with a patch. Thank you !
