tree-wide: add SD_ID128_MAKE_STR, remove LOG_MESSAGE_ID
Embedding sd_id128_t's in constant strings was rather cumbersome. We had SD_ID128_CONST_STR which returned a const char[], but it had two problems: - it wasn't possible to statically concatanate this array with a normal string - gcc wasn't really able to optimize this, and generated code to perform the "conversion" at runtime. Because of this, even our own code in coredumpctl wasn't using SD_ID128_CONST_STR. Add a new macro to generate a constant string: SD_ID128_MAKE_STR. It is not as elegant as SD_ID128_CONST_STR, because it requires a repetition of the numbers, but in practice it is more convenient to use, and allows gcc to generate smarter code: $ size .libs/elogind{,-logind,-journald}{.old,} text data bss dec hex filename 1265204 149564 4808 1419576 15a938 .libs/elogind.old 1260268 149564 4808 1414640 1595f0 .libs/elogind 246805 13852 209 260866 3fb02 .libs/elogind-logind.old 240973 13852 209 255034 3e43a .libs/elogind-logind 146839 4984 34 151857 25131 .libs/elogind-journald.old 146391 4984 34 151409 24f71 .libs/elogind-journald It is also much easier to check if a certain binary uses a certain MESSAGE_ID: $ strings .libs/elogind.old|grep MESSAGE_ID MESSAGE_ID=%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x MESSAGE_ID=%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x MESSAGE_ID=%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x MESSAGE_ID=%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x $ strings .libs/elogind|grep MESSAGE_ID MESSAGE_ID=c7a787079b354eaaa9e77b371893cd27 MESSAGE_ID=b07a249cd024414a82dd00cd181378ff MESSAGE_ID=641257651c1b4ec9a8624d7a40a9e1e7 MESSAGE_ID=de5b426a63be47a7b6ac3eaac82e2f6f MESSAGE_ID=d34d037fff1847e6ae669a370e694725 MESSAGE_ID=7d4958e842da4a758f6c1cdc7b36dcc5 MESSAGE_ID=1dee0369c7fc4736b7099b38ecb46ee7 MESSAGE_ID=39f53479d3a045ac8e11786248231fbf MESSAGE_ID=be02cf6855d2428ba40df7e9d022f03d MESSAGE_ID=7b05ebc668384222baa8881179cfda54 MESSAGE_ID=9d1aaa27d60140bd96365438aad20286
