Prototype without "inline" keyword breaks the build with some gcc
versions. Noticed by Alexander Graf.
Fix this by removing the inline keywork everywhere. Some functions
can't be inlined anyway as the are referenced using function pointers.
Beside that gcc does a pretty good job on auto-inlining these days.

On IA32 host or IA32 PAE host, at present, generally, we can't create
an HVM guest with more than 2G memory, because generally it's almost
impossible for Qemu to find a large enough and consecutive virtual
address space to map an HVM guest's whole physical address space.
The attached patch fixes this issue using dynamic mapping based on
little blocks of memory.
Each call to qemu_get_ram_ptr makes a call to qemu_map_cache with the
lock option, so mapcache will not unmap these ram_ptr.
Blocks that do not belong to the RAM, but usually to a device ROM or to
a framebuffer, are handled in a separate function. So the whole RAMBlock
can be map.

Like other Intel devices, e100 (eepro100) uses little endian byte order.
This patch was tested with these combinations:
i386 host, i386 + mipsel guests (le-le)
mipsel host, i386 guest (le-le)
i386 host, mips + ppc guests (le-be)
mips host, i386 guest (be-le)
mips and mipsel hosts were emulated machines.

QEMU sends frames smaller than 60 bytes to ethernet nics.
Such frames are rejected by real NICs and their emulations.
To avoid this behaviour, other NIC emulations pad received
frames. This patch enables this workaround for eepro100, too.
All related code is marked with CONFIG_PAD_RECEIVED_FRAMES,
so we can drop this in case QEMU's networking code is
ever changed.

Windows allows control transfers to pass up to 4k of data, so raise our
