6937487be7 libbb: reduce the overhead of single parameter bb_error_msg() calls 
Back in 2007, commit 0c97c9d437 ("'simple' error message functions by
Loic Grenie") introduced bb_simple_perror_msg() to allow for a lower
overhead call to bb_perror_msg() when only a string was being printed
with no parameters. This saves space for some CPU architectures because
it avoids the overhead of a call to a variadic function. However there
has never been a simple version of bb_error_msg(), and since 2007 many
new calls to bb_perror_msg() have been added that only take a single
parameter and so could have been using bb_simple_perror_message().

This changeset introduces 'simple' versions of bb_info_msg(),
bb_error_msg(), bb_error_msg_and_die(), bb_herror_msg() and
bb_herror_msg_and_die(), and replaces all calls that only take a
single parameter, or use something like ("%s", arg), with calls to the
corresponding 'simple' version.

Since it is likely that single parameter calls to the variadic functions
may be accidentally reintroduced in the future a new debugging config
option WARN_SIMPLE_MSG has been introduced. This uses some macro magic
which will cause any such calls to generate a warning, but this is
turned off by default to avoid use of the unpleasant macros in normal
circumstances.

This is a large changeset due to the number of calls that have been
replaced. The only files that contain changes other than simple
substitution of function calls are libbb.h, libbb/herror_msg.c,
libbb/verror_msg.c and libbb/xfuncs_printf.c. In miscutils/devfsd.c,
networking/udhcp/common.h and util-linux/mdev.c additonal macros have
been added for logging so that single parameter and multiple parameter
logging variants exist.

The amount of space saved varies considerably by architecture, and was
found to be as follows (for 'defconfig' using GCC 7.4):

Arm:     -92 bytes
MIPS:    -52 bytes
PPC:   -1836 bytes
x86_64: -938 bytes

Note that for the MIPS architecture only an exception had to be made
disabling the 'simple' calls for 'udhcp' (in networking/udhcp/common.h)
because it made these files larger on MIPS.

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.
