754e799d35 js: disallow bulk set data on key from outside
--

* src/Key.js Key class is not exported anymore, as it should not be
  used directly anywhere. setKeyData is no more a method of the Key,
  (optional) data are now validated and set on Key creation and on
  updates, both from within this module, thus no longer exposing
  setKeyData to the outside.
* createKey now gained an optional parameter which allows to set Key
  data at this point.

ea43158d40 js: avoid async getters
--

* src/Key.js get armored was returning a promise on async keys.
  As getters should not do that, it returns an error in this case.

43cff51364 js: wrong object assumed in recent commit
--

* src/Keyring.js I wrongly assumed an object to be a GPGME_Key,
  it was the raw answer from nativeMessaging instead. Now it returns
  a GPGME_Key again.

715cdc0d7d js: get default key fixes
--

* src/Keyring.js: The answer was not parsed correctly, so a config was
  being ignored.

* If no config is set, we return the first non-invalid key with a
  secret, instead of the first key (which may be e.g. an expired one)

aeb065acc9 js: simplify getDefaultKey
--

* src/Keyring.js: In case no default Key is set in configuration,
  only Keys reported as having a secret part should be considered
  for default Keys, avoiding some extra requests.

622db0d1de js: consistently return uppercase fingerprint
--

* src/Key.js: the fingerprint returned by a Key is now always upper
  case hex, even if the constructor had lower case input. This is to be
  more consistent with gpgme and to be more readable and reliable in
  comparisions.

If the build directory has too long path, gpgme could fail.
This is similar to

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=847206

In order to fix that, this patch extracts the GNUPGHOME variable
to be presented directly in the Makefile and thus overridable by
command line option.

A build system can then create a symlink to the GNUPGHOME directory
in /tmp and use that symlink as the GNUPGHOME directory
thus making the path very short.

--
* src/ [Connection, Error, Key, Keyring, MEssage, Signature, gpgmejs]:
    Functions and values that are not meant to be overwritten are now
    moved into their constructors, thus eliminating the possibility of
    overwrites after initialization.

* Key: The mode of use (synchronous cached, or async promises) ivs now
  determined at initialization of that Key. The property Key.isAsync
  reflects this state.

* unittests: fixed old Key syntax for testing.

* Message.js isComplete is now a method and not a getter anymore.

* Added some startup tests.

b18b96fb36 js: clean up test extension
--

Tests will now run with one instance of gpgmejs each block,
which reduces overhead. Readability is (hopefully) improved),
some negative tests are added.

There is still a performance problem in base64 encoding/decoding,
which causes some tests to fail due to time out.

4d1642b11e docs: python bindings howto
* Fixed and tested the changes necessary for org-mode to correctly
  parse pythonic (Python 3) indentation.
* Updated the source blocks to recommended upper case for BEGIN_SRC
  and END_SRC.
* Tested and confirmed XHTML output matches correct examples.
* Tested against pseudo-control output via exporting from org-mode to
  org-mode and then exporting that to XHTML.  Remaining differences
  appear to be discarding the custom tags used to provide X[HT]ML id
  elements to each section which does not appear to offer any benefit.
* Exporting directly to XHTML or other HTML output should no longer
  cause problems, but if there are any then the first step should be
  exporting from org-to-org and then exporting that to XHTML.

This is a best effort feature to not output plaintext after a
decryption failure (e.g. due to no or broken authenticated
encryption).  It always work when using a memory object and reading it
after the decryption but it can't work reliable when the user is
reading from the data object while the decryption process is still
running.

This is quite a large change because the data objects and the context
objects are allowed to be owned by different threads.  Thus a
synchronization is needed and we do this with a global table of all
data objects to which the context objects can do soft-linking via a
unique data object serial number.

calloc takes two arguments so to be able to detect integer overflow.
Thus if we switch from malloc to calloc we should utilize that.

The Problem is that on my western windows system GnuPG
gets CP 437 as GetConsoleOutputCP and prints in that codepage.
In a W32 GUI Application we get 0 as GetConsoleOutputCP and 1252
with GetACP.

The only thing that seemed to somehow match was GetOEMCP but
that might just be luck and it might still be broken in
other windows languages.

This code is also used in Kleopatra so it might make sense
to make it public once it is demonstrated that it works on
most systems.

The call to parse_hex4 checks that only hex digits follow and in the
error case returns 0.  However, by the time of the combined check for
an invalid value and the error PTR has already been set to the last
hex character and thus if the end-of-string or a quote character was
one of the bad hex digits the loop will miss the end of the string
which does not match with the simple buffer length allocation test at
the begin of the function.
