8ef5c4cf9d Set DEFAULT_TEXT_DOMAIN in lib/util's Makefile not individual .c files.
We no longer need to include sudo_gettext.h before sudo_compat.h

446ae3f507 Include string.h unconditionally and only use strings.h for strn?casecmp()
In the pre-POSIX days BSD had strings.h, not string.h.
Now strings.h is only used for non-ANSI string functions.

dd88460800 We no longer need to include headers we don't use for sudo*.h files.
Previously we needed to include headers required by the various
sudo*h files.  Now those files are more self-sufficient and we
should only include headers needed by code in the various .c files.

83d1bee918 Rename sudo_parse_host_port -> iolog_parse_host_port and mv to lib/iolog
It is not used outside of the I/O log client and server and the
host:port syntax may change in the future.

6901fc97ac Add a ClientHello message that client sends to the server.
This makes it easier to detect a plaintext client sending to a
TLS port.  Without this, the TLS server will be silent as it
waits for the client to initiate the TLS connection.

e5f8214c0a Remove the tls parameter from the ServerHello message.
The TLS connection is now initiated before ServerHello is received.

b5a317aeb9 Add support for a tls flag in sudo_parse_host_port().
If the string "(tls)" appears at the end, the tls flag is set to true
and the default tls port is used if necessary.

0460008c5b Handle EAGAIN like we do ENOMEM from poll() and select().
On some systems, poll() and select() can return EAGAIN instead
of ENOMEM if there is a kernel resource shortage.  In this case
we just re-enter the event loop and retry.

2b1e986572 Do not call poll(2) or ppoll(2) with nfds > RLIMIT_NOFILE.
Both poll(2) and ppoll(2) will return EINVAL if the nfds function
argument is larger than the max files per process resource limit.
Prevent this by limiting the max number entries in the pfds[] array
to the RLIMIT_NOFILE soft limit.

01ceba0445 Simply the JSON parsing code a bit.
We can use a single stack for nested objects and arrays.
There is also no need to track the current object and array separately.
This allows us to remove the array special case when assigning a value.

7e5641bc76 Fix unlocking of an entire file with lockf().
Since lockf() uses the files's current offset, we need to seek to
the start of the file to unlock the entire file.
