API error should probably be debug
Remove netmask
Formatting
Allow NULL user object filter

If the DN of the user object can be constructed from attributes in the request, there's no need to apply a filter, and scope = base can be used.
Revert "tls: Set umask before creating temporary file"

This reverts commit 1fc1558e7ac11102a4bc479a57de76c4f4f42c46.

There are a few issues with this change.

1) verify_tmp_dir is created 0700 *before* mkstemp() is called
   So the umask for the temporary file doesn't matter

2) the server is threaded, and umask() is *global* to the process
   So there is no "before" mkstemp() and "after" mkstemp().

The Coverity warning is (in this case) a false positive.
Should be T_INVALID not T_OP_INVALID
Rename map_from_str to map_from_fields
tok should be a bool
Add getop (get an operator)
Fixup map_from_str to work correctly with list qualifiers
Added RFC 7155
Set prefix for Client-Src-IP-Address, too
Depend on krb5-libs, not krb5
Update ChangeLog
Fixes for deprecated libcouchbase functions
Fix previous commit... should be setting prefix on src_ipaddr field
Check for null leaf values when parsing JSON structures. Fixes #790
Fix dynamic client debug messages
fr_ipaddr_cmp should compare prefixes too 0.0.0.0/1 != 0.0.0.0/0
Set CURLOPT_NOSIGNAL in rest module

This is required for multithreaded applications (see http://curl.haxx.se/libcurl/c/libcurl-tutorial.html#Multi-threading). Once in a while, this would result in a longjump error:

    *** longjmp causes uninitialized stack frame ***: freeradius terminated

The crash occured about once or twice per hour while under continuous load, there is no definite way to reproduce it. I haven't seen it anymore with these changes after several hours of testing.
