* common/openpgp-oid.c (openpgp_oidbuf_to_str): Factor most code out
to ...
(openpgp_oidbuf_to_str): new.
(openpgp_oidbuf_is_ed25519): New.
(openpgp_oidbuf_is_cv25519): New.
--
At some places it is more convenient (and faster) to directly work on
buffers and avoid the way via opaque MPIs. These 3 new functions
allow for that.

* common/openpgp-oid.c (openpgp_is_curve_supported): Add optional arg
R_ALGO and change all callers.

* g10/options.h (struct opt): Add field DEF_NEW_KEY_ALGO.
* g10/gpg.c (oDefaultNewKeyAlgo): New enum.
(opts): New option "--default-new-key-algo".
(main): Set the option.
* g10/keygen.c: Remove DEFAULT_STD_ FUTURE_STD_ constants and replace
them by ...
(DEFAULT_STD_KEY_PARAM, FUTURE_STD_KEY_PARAM): new string constants.
(get_keysize_range): Remove arg R_DEF and return that value instead.
Change all callers.
(gen_rsa): Use get_keysize_range instead of the removed
DEFAULT_STD_KEYSIZE.
(parse_key_parameter_part): New function.
(parse_key_parameter_string): New function.
(quick_generate_keypair): Refactor using parse_key_parameter_string.
(generate_keypair): Ditto.
(parse_algo_usage_expire): Ditto.
--
This new option is intended to be used in the forthcoming
--set-profile command of gpgconf. It allows to provide a gpg
configuration with custom defaults for a new key using the simple
commands which use the default algorithm set.

It is possible that an opaque MPI stores just a NULL pointer. Take

this case because at least a length byte is required.

* common/t-openpgp-oid.c (BADOID): New.
(test_openpgp_oid_to_str): Add test cases.
--
The code has an obvious error by not considering invalid encoding for
arc-2. A first byte of 0x80 can be used to make a value of less then
80 and we then subtract 80 from that value as required by the OID
encoding rules. Due to the unsigned integer this results in a pretty
long value which won't fit anymore into the allocated buffer.
The fix is obvious. Also added a few simple test cases. Note that we
keep on using sprintf instead of snprintf because managing the
remaining length of the buffer would probably be more error prone than
assuring that the buffer is large enough. Getting rid of sprintf
altogether by using direct conversion along with membuf_t like code
might be possible.

--
Due to the previous change we now usually store the OID with the
private key and not the name. Thus during import we do not anymore
need to map the name to an oid but can use the oid directly. We fix
that by extending openpgp_curve_to_oid to allow an oidstr as input.

--
For ECC it seems to be better to show the name of the curve and not
just the size of the prime field. The curve name does not anymore fit
into the "<size><letter>" descriptor (e.g. "2048R") and a fixed length
format does not work either. Thus the new format uses
"rsa2048" - RSA with 2048 bit
"elg1024" - Elgamal with 1024 bit
"ed25519" - ECC using the curve Ed25519.
"E_1.2.3.4" - ECC using the unsupported curve with OID "1.2.3.4".
unless --legacy-list-mode is given. In does not anymore line up
nicely in columns thus I expect further changes to this new format.
