The threee tags `<name>`, `</name>` and `<command>` were frequently used
with a leading space that this removes. The reason this habbit is so
widespread in testcases is probably that they have been copy and pasted.
Hence, fixing them all now might curb this practice from now on.
Closes#12028
When parsing the "qop=" parameter of the digest authentication, and the
value is provided within quotes, the list of values can have leading
white space which the parser previously did not handle correctly.
Add test case 388 to verify.
