a541314b1f ntpd: add support for MD5/SHA1 message authentication
Add support for MD5 message authentication as described in RFC 5905.
This patch also supports SHA1 authentication.

The key file format is the same file format as used by ntpd.
The configuration file format follows standard Unix conventions
(# comments) with lines consist of the following fields separated by whitespace:
<key identifier, [1,65535]> <SHA1|MD5> <an ASCII string of up to 20 characters|an octet string [a-zA-F0-9] of up to 40 characters>.

Support the "source-directory" stanza from ifupdown[1]. source-directory
will include all files in the named directory. Similar to the Busybox
version of the "source" stanza, this version of source-directory does
not currently support shell wildcards.

We only check that the stanza starts with "source-dir" as ifupdown does[2].

9b1c8bf89b ntpd: show real, unclamped delays on low-latency networks
On fast network, I've seen "delay:0.002000" shown for all packets,
thus completely losing information on what real delays are.

The new code is careful to not reject packets with tiny delays
if the delay "grows a lot" but is still tiny:
0.000009 is "much larger" than 0.000001 (nine times larger),
but is still very good small delay.

79153cb6bc htpd: increase MIN_FREQHOLD by 3
This means we'll start correcting frequency ~5 minutes after start,
not ~3.5 ones.

With previos settings I still often see largish ~0.7s initial offsets
only about 1/2 corrected before frequency correction kicks in,
resulting in ~200ppm "correction" which is then slowly undone.

5cb4f9081f tls: fix to handle X.509 v1 certificates correctly
The syntax of public key certificates can be found in RFC 5280 section
4.1. The relevant part of the syntax is the following:

  TBSCertificate  ::=  SEQUENCE  {
    version         [0]  EXPLICIT Version DEFAULT v1,
    serialNumber         CertificateSerialNumber,
    ... remaining fields omitted ...
  }

The version field has a default value of v1. RFC 5280 section 4.1.2.1
says the following:

  If only basic fields are present, the version SHOULD be 1 (the value
  is omitted from the certificate as the default value); however, the
  version MAY be 2 or 3.

To help detect if the version field is present or not, the type of the
version field has an explicit tag of [0]. Due to this tag, if the
version field is present, its encoding will have an identifier octet
that is distinct from that of the serialNumber field.

ITU-T X.690 specifies how a value of such a type should be encoded with
DER. There is a PDF of X.690 freely available from ITU-T. X.690 section
8.1.2 specifies the format of identifier octets which is the first
component of every encoded value. Identifier octets encode the tag of a
type. Bits 8 and 7 encode the tag class. Bit 6 will be 0 if the encoding
is primitive and 1 if the encoding is constructed. Bits 5 to 1 encode
the tag number.

X.690 section 8.14 specifies what the identifier octet should be for
explicitly tagged types. Section 8.14.3 says if implicit tagging is not
used, then the encoding shall be constructed. The version field uses
explicit tagging and not implicit tagging, so its encoding will be
constructed. This means bit 6 of the identifier octet should be 1.

X.690 section 8.14 and Annex A provide examples. Note from their
examples that the notation for tags could look like [APPLICATION 2]
where both the tag class and tag number are given. For this example, the
tag class is 1 (application) and the tag number is 2. For notation like
[0] where the tag class is omitted and only the tag number is given, the
tag class will be context-specific.

Putting this all together, the identifier octet for the DER encoding of
the version field should have a tag class of 2 (context-specific), bit 6
as 1 (constructed), and a tag number of 0.

43b9235f66 udhcp: fix use of trim() in udhcp_str2optset()
trim() modifies the string in place if needed and returns a pointer to
the end of the resulting string. Update udhcp_str2optset() so it no
longer sets the value of 'val' to the return value of trim().

2aeb201c97 libbb: new option FEATURE_ETC_SERVICES: if off, /etc/services reads often avoided
In practice, "wget http://host.com/" always uses port 80.
People explicitly set non-standard ports via options or parameters
("telnet 1.2.3.4 567" or "telnet 1.2.3.4 ftp") instead of modifying
/etc/services.
