A handful of code paths have been corrected to check return values
from functions like curl_easy_duphandle(), deflateInit(), lseek(),
dup(), and strbuf_getline_lf(), resolving several Coverity warnings
about unchecked returns.
* js/coverity-unchecked-returns-fix:
bisect: handle dup() failure when redirecting stdout
bisect: check get_terms return at all call sites
bisect: check strbuf_getline_lf return when reading terms
transport-helper: warn when export-marks file cannot be finalized
transport-helper: check dup() return in get_exporter
compat/pread: check initial lseek for errors
last-modified: handle repo_parse_commit() failures
reftable tests: check reftable_table_init_ref_iterator() return
reftable/block: check deflateInit() return value
reftable: handle block-writer initialization errors
config: propagate launch_editor() failure in show_editor()
http: die on curl_easy_duphandle failure in get_active_slot
