Fix identified by Mikulas Patocka.

The problem is that Map_ReadW reads 16-bit words from guest's memory and stores them in host-endian-byte-order in xq_turbo_init_block.  Most entries in xq_turbo_init_block are 16-bit words (thus it is ok that they are stored in host-endian-byte-order), but there are three fields in this data structure which are referenced as byte oriented fields. (phys, hash_filter and bootpassword).  These fields need to be handled in byte order to be properly interpreted.
Fixes to infinite loop issues found by Mikulas Patocka
Removed recently linked dependence of VHD support on Large File support.  VHDs can be supported without large file support up to the limits a system without large file support (i.e. 2GB).  Fixes issue #35
HP-UX port supplied by Mikulas Patocka
Fixed clk_help to display the correct device name for the VAX TODR implementations
Added '.' as a legal character in a register name (From Harry Reed)
Merge remote-tracking branch 'jguillaumes/master'
Changed use of compile #defines which start with a _ character to not do this since defined symbols starting with _ are reserved to local compiler/runtime implementations in the C language.  This addresses issue #32
Fixed misspelled include guard for the definition of SERHANDLE.
Start sleep calibration for *nix platforms on a clock tick
Exclude LTO from gcc builds when compiler isn't known to support it.
Remove compiler warnings generated by newer clang compiler
Added support for newer clang compilers on OSX and more flexible cases for libpcap components built from www.tcpdump.org source code
Cleanup compiler warnings on Solaris and newer OSX clang compilers.

Add Large File support on Solaris
Compiler suggested cleanups
Added indication of idle/throttling capabilities and the OS clock tick size to the SHOW VERSION output
Adjusted minimum wait time to allow RKLFMT to properly complete formatting an RK disk
Use the same sleep API to determine the host minimal sleep time that will be used depending on whether ASYNCH_IO is enabled
Cleanup for build on VMS
Fix to properly reference the correct routine during initial clock calibration introduced in commit: c45a377c7
