vmstate: Add support for two dimensional arrays

Add support for migrating two dimensional arrays, by defining
a set of new macros VMSTATE_*_2DARRAY paralleling the existing
VMSTATE_*_ARRAY macros. 2D arrays are handled the same for actual
state serialization; the only difference is that the type check...

savevm: Add VMSTATE_UINTTL_EQUAL helper

This adds an _EQUAL VMSTATE helper for target_ulongs, defined in terms of
VMSTATE_UINT32_EQUAL or VMSTATE_UINT64_EQUAL as appropriate.

savevm: Add VMSTATE_FLOAT64 helpers

The current savevm code includes VMSTATE helpers for a number of commonly
used data types, but not for the float64 type used by the internal floating
point emulation code. This patch fixes the deficiency.

savevm: Add VMSTATE_STRUCT_VARRAY_POINTER_UINT32

Currently the savevm code contains a VMSTATE_STRUCT_VARRAY_POINTER_INT32
helper (a variably sized array with the number of elements in an int32_t),
but not VMSTATE_STRUCT_VARRAY_POINTER_UINT32 (... with the number of...

savevm: Fix bugs in the VMSTATE_VBUFFER_MULTIPLY definition

The VMSTATE_BUFFER_MULTIPLY macro is misnamed - it actually specifies
a variably sized buffer with VMS_VBUFFER, so should be named
VMSTATE_VBUFFER_MULTIPLY. This patch fixes this (the macro had no current...

savevm: Add VMSTATE_UINT64_EQUAL helpers

The savevm code already includes a number of *_EQUAL helpers which act as
sanity checks verifying that the configuration of the saved state matches
that of the machine we're loading into to work. Variants already exist...

This makes it possible to do blocking writes directly to the socket,
with no buffer in the middle. For RAM, only the migration_bitmap_sync()
call needs the iothread lock. For block migration, it is needed by...

hw: move fifo.[ch] to libqemuutil

fifo.c is generic code that can be easily unit tested. So it
belongs in libqemuutil.
