"dont compress = *", by request of Tridge. Instead, mention the difference
in the man page. Also, put in a shortcut in set_compression() to recognize
"*" earlier instead of going through malloc/strtok/fnmatch/free cycle.
1) handle 64 bit file offsets in the token code. I wonder how large
bit files worked up till now?
2) send a null token when we have passed over a large lump of data
without finding a token match. This reduces the number of IOs
considerably as it removes the need for seeks/reads on the checksum
calculation and literal send code. This is not enabled yet for the
compressed case as the deflate token code can't handle it yet.
files up to 2^64 bytes in size. Now I just need to find enough disk
space to test this :-)
The 64 bit offset code only works if off_t is 64 bits (or bigger!) on
both ends of the link. If one end tries to send a file greater than
2^31 in size and the other end doesn't support it then rsync will
abort.
This commit also cleans up some static declarations so they are in a
unitinitialised segment to save load time.
