Add 'http-compression=auto' mode on the client, now used by default.

Following up on the recently added support for LZ4 compression, this patch

introduces the new possible 'auto' mode for our client 'http-compression'

configuration option, and starts using it by default.

The previously used default was 'http-compression=yes', and the new 'auto'

mode is a small, but an important tweak to its behavior. In the new mode,

the HTTP compression is still being used, but the negotiating is tweaked

to favor svndiff2 with LZ4 compression when working over local networks.

The reasoning behind this is that for local networks it probably makes sense

to favor compression speed of LZ4 instead of the better compression ratio

from zlib-5, which has been used previously.

To separate local and wide area networks, we use the connection latency of

the initial OPTIONS request obtained with serf_connection_get_latency().

Add support for read-only access to svn_config_t. In read-only mode,

concurrent multi-threaded access to the same config data structure is


We introduce a simple private API function that allows us to switch

a config struct into r/o mode (one-way as the reversal seems dangerous).

Part of that transition is expanding all values to prevent internal

state change upon later read access.

The code expects r/o structs not to be written to and simply ignores

write ops in release mode. In debug mode, an assert()ion is triggered.

This is because the existing setter functions don't provide error

return values.
