763ce13b0b dropbear: allow disabling support for scp
If not needed, disabling scp allows for a nice size reduction.

Dropbear executable size comparison:

153621 bytes (baseline)
133077 bytes (without scp)

In other words, we trim a total of 20544 bytes.

01964148c6 dropbear: split ECC support to basic and full
- limit ECC support to ec*-sha2-nistp256:

- provide full ECC support as an option:
  * DROPBEAR_ECC_FULL brings back support for ec{dh,dsa}-sha2-nistp{384,521}
- update feature costs in binary size

a816e1eac7 dropbear: make ssh compression support configurable
Adds config option to enable compression support which is usefull
when using a terminal sessions over a slow link. Impact on binary
size is negligible but additional 60 kB (uncompressed) is needed for
a shared zlib library.
