Document session-state some more
Added -D option to mirror radclient
Load internal dictionary, for Packet-Src-IP-Address, etc.
IDs are signed for DHCP.  Closes #797.

We don't want integer overflow.
Fix %{escape:} and %{unecape:} to work correctly with UTF8 safe characters
Quiet GCC
Fix infinite loop in fr_fault if initial pattach fails (indicating process is running under debugger), and process receives either SIGUSR1 or SIGUSR2
Debugging info to help find out why the ptrace attach failed
Better checks for duplicates.

If the old packet is in RESPONSE_DELAY or CLEANUP_DELAY,
we can delete the old packet.  This is really only for DHCP.
More fixes for fr_debugger_attached
Quiet GCC
Add reply attributes, not over-write them
Typo
Allow all UTF-8 characters
Fix compile error
Another typo
Allow TLS 1.1 and 1.2
Fix fr_utf8_strchar() and tests

allowed characters shouldn't be escaped in the test.

the function returns const

it checks for fr_utf8_char() of str, not char the second time
around
Add libcap-dev dependency for travis and debian packages
Link to libcap to determine process capabilities

This lets us know whether the debugger attach check is failing because
we don't have CAP_SYS_PTRACE or because there really is another
debugger attached already.
