Subject: docs/libcurl: remove ancient version references
X-Git-Tag: rc-8_17_0-2~513
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=d7d32ad9b9e9dbf7a372689affd497dcec18df6e;p=thirdparty%2Fcurl.git

docs/libcurl: remove ancient version references

To make the texts easier on the eye.

- Remove most free text references to curl versions before 7.60.0 (May
  2018)
- Leave those present in a HISTORY section

Most of them are already documented in symbols-in-versions anyway.

Closes #18530
