85875be00f Sometimes dst write cb fires but not event cb, especially if the listener cb is not finished yet, so the conn stalls. This is a workaround for this error condition, nothing else seems to work.

ac3e845fbe Test dnsbase and evbase for !NULL before freeing 
Fix segmentation fault upon exiting the main loop that was introduced
when evdns initialization was made optional, resulting in dnsbase
elements not always being initialized.

0e2b748bba Only init DNS when DNS is required by proxy specs 
Only initialize evdns if DNS lookups are actually required by the loaded
proxy specifications.  This allows sslsplit to work in non-DNS modes in
situations where the local DNS resolver does not work, such as for local
use on a system without network connectivity.  Currently, only SNI based
proxy specs require DNS.  On systems without network connectivity, DNS
subsystem init may fail due to /etc/resolv.conf being (temporarily)
unavailable.

fb2841f645 Zero allocated elements before initializing them 
For some error conditions, the error handler depends on
ctx->thr[idx]->dnsbase to be zeroed expicitly after allocation.
To prevent this type of error, zero all allocated memory even
though it will get written to in any case.

d3abdfd5dc Fix race condition on proxy startup failure 
Yield the CPU in the main thread until the proxy thread manager is fully
started.  Otherwise, the main thread could free the proxy thread manager
while the threads are still starting up, leading to a deadlock.
