Bug#970520: wesnoth: Crash on starting wesnoth - stack smash detected

Dear Maintainer,
I could reproduce this stack smashing inside a testing amd64 VM.
The stack canary gets overwritten in the stack below.
It looks like there is a disagreement of wesnoth and wolfssl in
the size of sha/hasher wc_Sha/WOLFSSL_SHA_CTX, the first allocates
112 bytes, the latter thinks it got a pointer to 128 bytes.
Because wesnoth got built against libwolfssl-dev 4.4.0+dfsg-2,
and this error manifests when run with libwolfssl24 4.5.0+dfsg-3,
I am still unsure if this might be a ABI break.
At least when installing 4.4.0+dfsg-2 in function wc_InitSha_ex
sizeof(*sha) shows also 112. And the game starts up.
@Felix Lechner: Hope it is ok to add you in CC?
Kind regards,
Bernhard
