Inconsistent enum names in HUAWEI extensions

[lexaknyazev]

The #659 PR added two new extensions with the following update for the GL headers:

#ifndef GL_HUAWEI_program_binary
#define GL_HUAWEI_program_binary 1
#define GL_HUAWEI_PROGRAM_BINARY          0x9771
#endif /* GL_HUAWEI_program_binary */

#ifndef GL_HUAWEI_shader_binary
#define GL_HUAWEI_shader_binary 1
#define GL_HUAWEI_SHADER_BINARY           0x9770
#endif /* GL_HUAWEI_shader_binary */

The enums should have been called GL_PROGRAM_BINARY_HUAWEI and GL_SHADER_BINARY_HUAWEI or GL_HUAWEI_PROGRAM_BINARY_HUAWEI and GL_HUAWEI_SHADER_BINARY_HUAWEI because an extension vendor prefix becomes a suffix in GL symbols. Also having macros that differ only in casing is quite error-prone.

Other similar enums, for comparison:

// GL_AMD_program_binary_Z400
#define GL_Z400_BINARY_AMD                0x8740

// GL_ANGLE_program_binary
#define GL_PROGRAM_BINARY_ANGLE           0x93A6

// GL_ARM_mali_shader_binary
#define GL_MALI_SHADER_BINARY_ARM         0x8F60

// GL_ARM_mali_program_binary
#define GL_MALI_PROGRAM_BINARY_ARM        0x8F61

// GL_DMP_shader_binary
#define GL_SHADER_BINARY_DMP              0x9250

// GL_DMP_program_binary
#define GL_SMAPHS30_PROGRAM_BINARY_DMP    0x9251
#define GL_SMAPHS_PROGRAM_BINARY_DMP      0x9252

// GL_IMG_shader_binary
#define GL_SGX_BINARY_IMG                 0x8C0A

// GL_IMG_program_binary
#define GL_SGX_PROGRAM_BINARY_IMG         0x9130

// GL_MESA_program_binary_formats
#define GL_PROGRAM_BINARY_FORMAT_MESA     0x875F

// GL_FJ_shader_binary_GCCSO
#define GL_GCCSO_SHADER_BINARY_FJ         0x9260

// GL_VIV_shader_binary
#define GL_SHADER_BINARY_VIV              0x8FC4

Thanks. I'll try fix it using GL_SHADER_BINARY_HUAWEI/GL_PROGRAM_BINARY_HUAWEI and add an alias to exising definition so existing apps won't break down due to the modification.
