Add OpenSSL compat: BIO_get_new_index, i2d_PUBKEY_bio, OpenSSL_version

[Roy-Carter]

Description

As part of the continuous of the integration of openssl to wolfssl i've come across a few missing functions needed for OpenSSL-compat APIs: BIO_get_new_index() (unique custom BIO type IDs, 128–255), i2d_PUBKEY_bio() (write public-key DER to a BIO), and OpenSSL_version(type) handling for the six standard OPENSSL_* selector constants (plus unknown → version string). Headers/macros updated under OPENSSL_EXTRA / !NO_BIO as appropriate.

Testing

Ran ./tests/unit.test with -~BIO_get_new_index, -~OpenSSL_version, and -~i2d_PUBKEY_bio (substring filters). All passed.

Checklist

• [*] added tests
• updated/added doxygen
• updated appropriate READMEs
• Updated manual and documentation

[Roy-Carter]

@julek-wolfssl can you please run the workflow on this ?

[wolfSSL-Bot]

Can one of the admins verify this patch?

Okay to test. Contributor agreement on file.

hey @julek-wolfssl would you mind checking why the packaging test failed ? looks like a false positive , I don't see any errors there on the log regarding the build process of wolfssl which can relate to my code , or maybe I missed something

@dgarske @julek-wolfssl can we re-test ? fixed build errors

[julek-wolfssl]

Retest this please.

[Roy-Carter]

openvpn test failed due to what seems like diffs from master and not my code , i rebased to master can we re-run workflow @julek-wolfssl

[Roy-Carter]

@julek-wolfssl @dgarske can we re-run workflows ? there was a conflict on two of the test files

[dgarske]

Jenkins retest this please

[julek-wolfssl]

Please rebase before pushing to this branch.

[Roy-Carter]

@julek-wolfssl @dgarske I updated the branch and rebased to master , all tests passed before so i assume it only relates to the branch being out-dated .

[dgarske]

Jenkins okay to test

Just the one copilot comment to address and CI failures. Thanks @Roy-Carter

Hey , Just pushed the change , I assume the failures happened due to the openssl fix copilot suggested the fix for since I see that those cases now run fine
