This should always be defined and including config.h is a requirement.

encode_32 already deals with endian, don't swap twice.
Tested with a ppc64 server machine and a x64 client.
This looks the reverse of a previous patch (59c6c82) supposed to fix big
endian machine. encode_32 has been always:
static inline void encode_32(Encoder *encoder, unsigned int word)
{
encode(encoder, (uint8_t)(word >> 24));
encode(encoder, (uint8_t)(word >> 16) & 0x0000ff);
encode(encoder, (uint8_t)(word >> 8) & 0x0000ff);
encode(encoder, (uint8_t)(word & 0x0000ff));
}
while encode basically is similar to a putc on a FILE stream so is writing
numbers from host endian to big endian order.
The "main" endian (the one more tested since ever) is host/guest being
little endian. So if you call encode_32 with a 0x01020304 you get 4 bytes
in the order 1, 2, 3, 4.
Before and after 59c6c82 LZ_MAGIC was defined as:
#define LZ_MAGIC (*(uint32_t *)"LZ ")
so on little endian this was 0x4c, 0x5a, 0x20, 0x20 that is 0x20205a4c
which written through encode_32 become 0x20, 0x20, 0x5a, 0x4c so we can say
that at the end on the network we must have 0x20, 0x20, 0x5a, 0x4c.
On big endian however LZ_MAGIC got the value 0x4c5a2020 which written
through encode_32 get 0x4c, 0x5a, 0x20, 0x20 which is the opposite
expected. So patch 59c6c82 reverted the order having again 0x20, 0x20,
0x5a, 0x4c on the network.
However commit 5a7e587 (spice-common), in an attempt to avoid double
swapping on LZ, changed LZ_MAGIC to
#define LZ_MAGIC 0x20205a4c
breaking endianness again for GLZ code.

When GLZ code attempts to send a 64 bit integer the 8 top bit of
the lower (32 bits) part of the number are stripped due to a bug.

This commit changes all functions returning TRUE/FALSE from having an
'int' return value to 'bool'.
This way it's obvious that such a function is not going to return
anything else than TRUE or FALSE.
