Andri Yngvason 19538c9435 server: Fix encoding selection for sw frames
This fixes encoding selection when not using the --gpu option. Before this
change, raw encoding would always be selected.

Philipp Zabel affd7f3f6d Allow to query client-side cursor support
Add a function nvnc_client_supports_cursor() to enable the API user to
make an informed decision whether nvnc_set_cursor() can be expected to
make the client draw the cursor, or whether it has to be rendered into
the framebuffer.

Andri Yngvason 528eac51a3 Fix jpeg quality setting
The encoding identifiers are supposed to be interpreted as a range. I
interpreted the upper and lower limits as two discrete quality settings
instead, which is wrong.

Andri Yngvason 3ea068b90c server: Decrement n_pending_requests after dispathing encoding job
The request is as good as handled at that point. We don't want to squeeze
in another frame that the client didn't request before the encoding job
finishes. That would cause a negative pending count and the client would
stop getting updates.

Scott Moreau 783807c0b9 server: Fix possible crash on fragmented packet messages
The packets sent from the client especially for client cut text,
are typically sent in two packets, one for the message containing
the type and length and the other for the actual data. Sometimes
the first message is read but we still don't have the data yet.
We need to continue reading data to use the structure but this
revealed a bug. The client event handler was calling memmove()
with buffer_index as the size argument. This meant that it was
copying the wrong amount of data, resulting in garbage at the
end of the expected data. This patch fixes the problem by first
subtracting buffer_index from buffer_len and then moving buffer_len
worth of data, which is what was read into msg_buffer. The problem
possibly manifested itself with random crashes, after reading
random data.

Stefan Agner 8316994dfa use static for functions not used outside this compile unit
Add static for all functions only used inside the individual compile
units. This helps the compiler to potentially inline these functions.

Andri Yngvason 77b866096d Redesign framebuffer update loop
Rendering may now only happen inside the rendering callback. The user is
also allowed to change out the entire buffer in the callback.

The callback is triggered by nvnc_damage_region(), nvnc_damage_whole()
and/or framebuffer update requests.
