+Make libcurl respect the SSL_CERT_{DIR,FILE} variables by default. The variables
+are fetched during initialization to preserve thread-safety (curl_global_init(3)
+must be called when no other threads exist).
+
+This fixes network functionality in rust:cargo, and probably removes the need
+for other future workarounds.

-Description: Two fixes, cherry-picked from svn plus a CVE fix.
-I have removed the partial fixes for various system versions of poppler.
-
-r47469 Fix segfault in dvipdfm-x (XeTeX) on 1/2/4-bit transparent indexed PNGs.
-
-r47477 Fix a ptex regression for discontinuous kinsoku table.
-
-Also, via fedora (I got lost in svn) a critical fix for CVE-2018-17407

-tweaks to comply with texlive-bin-CVE-2018-17407.patch.
