Hello Jenkins Builder,

I'd like you to reexamine a change. Please visit

https://gerrit.osmocom.org/c/libosmocore/+/35474?usp=email

to look at the new patch set (#2).

utils: fix -Wsign-compare in definition of OSMO_STRBUF_CHAR_COUNT

We're seeing tons of -Wsign-compare warnings since I merged 0f59cebf:

include/osmocom/core/utils.h: In function 'size_t _osmo_strbuf_char_count(const osmo_strbuf*)': include/osmocom/core/utils.h:24:29: error: comparison of integer expressions of different signedness: 'long int' and 'long unsigned int' [-Werror=sign-compare] 24 | #define OSMO_MIN(a, b) ((a) >= (b) ? (b) : (a)) | ~~~~^~~~~~ include/osmocom/core/utils.h:309:16: note: in expansion of macro 'OSMO_MIN' 309 | return OSMO_MIN(sb->pos - sb->buf, sb->len - 1); | ^~~~~~~~

Interestingly enough, this -Wsign-compare problem has always been the case, even before commit 0f59cebf. And somehow this did not show up when building libosmocore.git, but only when building C++ projects (osmo-pcu and osmo-trx).

Perhaps it has something to do with how g++ compiles extern "C" code.
