Missing AV_CODEC_HW_CONFIG_METHOD_* enum in autogen

[Revan1985]

Hello, I have noticed that some enum (in my case AV_CODEC_HW_CONFIG_METHOD_*), are missing from Codec Hw section.

well enum has no type name - one day maybe

I als noticed this missing enum/constant
I think in this case you shoud do the following:

• find the longest common prefix of the enum values => AV_CODEC_HW_CONFIG_METHOD
• "clean" this name. remove the underscores, convert to CamelCase =>AvCodecHwConfigMethod
  (- if you want to make nicer, you could add a dictionary which contains the words which should be kept in the current format, like "AV" => AVCodecHwConfigMethod)
• If the generated string is let's say at least 5 characters => use that name, otherwise ignore the enum

Well, I guess, declare this in your code - profit. I rather not as need to deal with other 100+ edge cases otherwise. :)

enum {
/**
* The codec supports this format via the hw_device_ctx interface.
*
* When selecting this format, AVCodecContext.hw_device_ctx should
* have been set to a device of the specified type before calling
* avcodec_open2().
/
AV_CODEC_HW_CONFIG_METHOD_HW_DEVICE_CTX = 0x01,
/*
* The codec supports this format via the hw_frames_ctx interface.
*
* When selecting this format for a decoder,
* AVCodecContext.hw_frames_ctx should be set to a suitable frames

* must have been created on a device of the specified type.
*
* When selecting this format for an encoder,
* AVCodecContext.hw_frames_ctx should be set to the context which
* will be used for the input frames before calling avcodec_open2().
/
AV_CODEC_HW_CONFIG_METHOD_HW_FRAMES_CTX = 0x02,
/*

*
* This format can be selected without any additional configuration -

AV_CODEC_HW_CONFIG_METHOD_INTERNAL = 0x04,
/*
* The codec supports this format by some ad-hoc method.
*
* Additional settings and/or function calls are required. See the

*/
AV_CODEC_HW_CONFIG_METHOD_AD_HOC = 0x08,
};

Thank you.
Yes, I have already done in this way, just to inform you if needed.

There are some more missing enums. The first enum values are the following (some enums contains only 1 value)
AV_BUFFERSRC_FLAG_NO_CHECK_FORMAT => 3 values
(AV_CODEC_HW_CONFIG_METHOD_HW_DEVICE_CTX => 4 values)
AV_FRAME_CROP_UNALIGNED => 1 value
AV_HWFRAME_MAP_READ => 4 values
AV_OPT_FLAG_IMPLICIT_KEY =>1 value
AVFILTER_AUTO_CONVERT_ALL => 2 values

I'll do this but later - all of them have no name most probably I'll add a type where all will be listed as Constants. AV_...

Low prio now. Have to address size_t for different platforms

Look at this PR please. I'm not saying it's perfect, but at least it generates something
