curl: show headers in bold
The feature is only enabled if the output is believed to be a tty.
-J: There's some minor differences and improvements in -J handling, as
now J should work with -i and it actually creates a file first using the
initial name and then *renames* that to the one found in
Content-Disposition (if any).
-i: only shows headers for HTTP transfers now (as documented).
Previously it would also show for pieces of the transfer that were HTTP
(for example when doing FTP over a HTTP proxy).
-i: now shows trailers as well. Previously they were not shown at all.
--libcurl: the CURLOPT_HEADER is no longer set, as the header output is
now done in the header callback.

examples/progressfunc: make it build on older libcurls
This example was changed in ce2140a8c1 to use the new microsecond based
getinfo option. This change makes it conditionally keep using the older
option so that the example still builds with older libcurl versions.

pingpong: fix response cache memcpy overflow
Response data for a handle with a large buffer might be cached and then
used with the "closure" handle when it has a smaller buffer and then the
larger cache will be copied and overflow the new smaller heap based
buffer.

cookies: do not take cookie name as a parameter
RFC 6265 section 4.2.1 does not set restrictions on cookie names.
This is a follow-up to commit 7f7fcd0.
Also explicitly check proper syntax of cookie name/value pair.
New test 1155 checks that cookie names are not reserved words.

Fixes #2564
Closes #2566
To make builds with VS2015 work. Recent changes in VS2015 _IOB_ENTRIES
handling is causing problems. This fix changes the OpenSSL backend code
to use BIO functions instead of FILE I/O functions to circumvent those
problems.
This file wasn't included in commit 4af40b3646d3b09 which updated all
haxx.se http urls to https. The file was committed prior to that update,
but may have been merged after it and hence didn't get updated.
This change fixes strlen_url() and strcpy_url() in parallel to use a
common host-encoding independent criterion for deciding whether an URL
character must be %-escaped.
checksrc: force indentation of lines after an else
This extends the INDENTATION case to also handle 'else' statements
and require proper indentation on the following line. Also fixes the
offending cases found in the codebase.

http2: get rid of another strstr()
Follow-up to 1514c44655e12e: replace another strstr() call done on a

All occurrences of assignment within conditional expression in
os400sys.c rewritten into two steps: first assignment and then the check
on the success of the assignment. Also adjust related incorrect brace
positions to match project indentation style.
This was spurred by seeing "if((inp = input_token))", but while in there
all warnings were fixed.
There should be no functional change from these changes.
ctype: restore character classification for non-ASCII platforms
With commit 4272a0b0fc49a1ac0ceab5c4a365c9f6ab8bf8e2 curl-speficic
character classification macros and functions were introduced in
curl_ctype.[ch] to avoid dependencies on the locale. This broke curl on
non-ASCII, e.g. EBCDIC platforms. This change restores the previous set
of character classification macros when CURL_DOES_CONVERSIONS is
defined.

http2: avoid strstr() on data not zero terminated
It's not strictly clear if the API contract allows us to call strstr()
on a string that isn't zero terminated even when we know it will find
the substring, and clang's ASAN check dislikes us for it.
Also added a check of the return code in case it fails, even if I can't
think of a situation how that can trigger.

openssl: fix subjectAltName check on non-ASCII platforms
Curl_cert_hostcheck operates with the host character set, therefore the
ASCII subjectAltName string retrieved with OpenSSL must be converted to
