Subject: [PATCH] HPack: fix a Yoda Condition
Putting the variable on the LHS of a relational operation makes the
expression easier to read. In this case, we find that the whole
expression is nonsensical as an overflow protection, because if
name.size() + value.size() overflows, the result will exactly _not_
be > max() - 32, because UB will have happened.
To be fixed in a follow-up commit.
As a drive-by, add parentheses around the RHS.

Subject: [PATCH] HPack: fix incorrect integer overflow check
This code never worked:
For the comparison with max() - 32 to trigger, on 32-bit platforms (or
Qt 5) signed interger overflow would have had to happen in the
addition of the two sizes. The compiler can therefore remove the
overflow check as dead code.
On Qt 6 and 64-bit platforms, the signed integer addition would be
very unlikely to overflow, but the following truncation to uint32
would yield the correct result only in a narrow 32-value window just
below UINT_MAX, if even that.
Fix by using the proper tool, qAddOverflow.
Manual conflict resolutions:
- qAddOverflow doesn't exist in Qt 5, use private add_overflow
predecessor API instead
