tls: show human-readable error messages

Before this commit, verification exceptions had err.message set to the
OpenSSL error code (e.g. 'UNABLE_TO_VERIFY_LEAF_SIGNATURE').

This commit moves the error code to err.code and replaces err.message
with a human-readable error.  Example:

    // before
    {
      message: 'UNABLE_TO_VERIFY_LEAF_SIGNATURE'
    }

    // after
    {
      code: 'UNABLE_TO_VERIFY_LEAF_SIGNATURE',
      message: 'unable to verify the first certificate'
    }

UNABLE_TO_VERIFY_LEAF_SIGNATURE is a good example of why you want this:
the error code suggests that it's the last certificate that fails to
validate while it's actually the first certificate in the chain.

Going by the number of mailing list posts and StackOverflow questions,
it's a source of confusion to many people.
tls: make cert/pfx optional in tls.createServer()

Not all ciphers require the presence of a certificate.  Remove the
check in lib/_tls_wrap.js.

Fixes #6887.
src: don't mark addon_register_func as dllimport

addon_register_func and its cousin addon_context_register_func are type
definitions, dllimport and dllexport are name mangling directives, i.e.
they're quite unrelated concepts.  MinGW complains about mixing them
when cross-compiling native add-ons.

tracing: update to dtrace-provider style emission

Remove the last vestiges of macros from the JavaScript portion of the
build system.

Implement tracing module, allow basic registration of static probes
previously defined for dtrace/etw/systemtap to be expressed in these
primitives.
