Add re-exec for server
This allows ASLR to re-randomize the address
space for every connection, preventing some
vulnerabilities from being exploitable by
repeated probing.
Overhead (memory and time) is yet to be confirmed.
At present this is only enabled on Linux. Other BSD platforms
with fexecve() would probably also work though have not been tested.

Multi-binary compilation ======================== To compile for systems without much space (floppy distributions etc), you can create a single binary. This will save disk space by avoiding repeated code between the various parts. If you are familiar with "busybox", it's the same principle. To compile the multi-binary, first "make clean" (if you've compiled previously), then make PROGRAMS="programs you want here" MULTI=1 To use the binary, symlink it from the desired executable: ln -s dropbearmulti dropbear ln -s dropbearmulti dbclient etc then execute as normal: ./dropbear <options here>
