5791109707 Make the hardclock test optional
Known to fail on VMs (such as the buildbots), see eg
http://blog.badtrace.com/post/rdtsc-x86-instruction-to-detect-vms/

9bd0afdb22 Add guards for closed socket in net.c
This is particularly problematic when calling FD_SET( -1, ... ), but let's
check it in all functions.

This was introduced with the new API and the fact the net_free() now sets the
internal fd to -1 in order to mark it as closed: now using this information.

2505528be4 Rm obsolete defines for inline wiht MSVC
The "inline" keyword is supported since Visual Studio 2005 according to MSDN,
and we require Visual Studio 2010 or higher.

abc729e664 Simplify net_accept() with UDP sockets
This is made possible by the new API where net_accept() gets a pointer to
bind_ctx, so it can update it.

3d7d00ad23 Rename mbedtls_net_close() to mbedtls_net_free()
close() may be more meaningful, but free() is symmetric with _init(), and more
consistent with all other modules

0761733c1b Fix potential NULL dereference
We document that either of recv or recv_timeout may be NULL, but for TLS we
always used recv... Thanks Coverity for catching that.
(Not remotely trigerrable: local configuration.)

Also made me notice net_recv_timeout didn't do its job properly.

cdc26ae099 Add mbedtls_ssl_set_hs_authmode
While at it, fix the following:
- on server with RSA_PSK, we don't want to set flags (client auth happens via
  the PSK, no cert is expected).
- use safer tests (eg == OPTIONAL vs != REQUIRED)

f8ea856296 Change data structure of profiles to bitfields
- allows to express 'none' or 'all' more easily than lists
- more compact and easier to declare statically
- easier to check too

Only drawback: if we ever have more than 32 curves, we'll need an ABI change to
make that field a uint64_t.
