Create mobile-friendly directory listings

A typical mobile browser on a smartphone assumes a page without a "viewport"
<meta> tag is designed for desktop browsers. It displays the page in a
virtual window that simulates a wider screen and does not adjust it for
the phone's pixel density. The usual result is that the content on the page
looks small, and interacting with the page comfortably and precisely requires
zoom. This is currently the case with bozohttpd directory listing pages.

call this bozohttpd 20181204.

many clean ups:
- keep a list of special files and their human names
- remove (void) casts on bozo_http_error()
- fix a few more misuses of bozo_http_error()
- rename check_mapping() to check_remap() and perform some CSE
- switch away from ``%s'' to '%s'
- remove a bunch of #ifdef using new have_feature defines

two fixes reported by mouse:
- don't check contents of 'st' if stat(2) failed.
- round up instead of truncate. now 10000 byte files say 10kB not 9kB.

from CHANGES:

o reduce default timeouts, and add expand timeouts to handle the
initial line, each header, and the total time spent
o add -T option to expose new timeout settings
o minor RFC fixes related to timeout handling responses

old timeouts:
60 seconds for initial request like, 60 seconds per header line,
and no whole timeout (though the recent total header size changes
do introduce one that would be about 11 hours.)
new timeouts:
30 seconds for initial request like, 10 seconds per header line,
and a total request time of 600 seconds.


the new global timeout is implemented using CLOCK_MONOTONIC, with
a fallback to CLOCK_REALTIME if monotonic time is unavailable.


reject multiple Host: headers. besides being protocol standard,
this closes one additional memory leak found by JP. add a simple
test to check this.


clean up option and usage handling some.

and remove the 'username' member of bozohttpd_t since it is not
used outside of bozo_setup().

rename bozo_err/bozo_warn/bozo_asprintf to bozoerr/etc.
new rule is that function that mirror libc-style functions get no underscore.

several clean ups:

- bozostrdup() gains a request parameter, and uses it to determine
what sort of error handling is required
- bozo_strdup() dies
- size_arrays() reduced slightly, pushing error handling into the caller
- convert to size_t for some array indices
- bozo_set_pref() and bozo_init_prefs() gain httpd parameters
- apply a bunch of manual CSE to vastly reduce the number of times the
string "request->hr_httpd" appears.
- CGI parse_header() takes a request not httpd now

XXX: lua glue updated to call bozo_init_prefs() with htttpd parameter,

From Sergey Katsev at Coyote Point: fix bugs in request transformation and
CGI handling, including bin/40355 . There are two main changes here:

1) call process_cgi() after transform_request(), not before. Now it is
possible to have a default cgi handler catch a request for a path that
was produced by transformation, e.g. by index generation -- so now the
index can be "generated" by a CGI if that is what the user desires.

2) More clearly distinguish "file" from "query" portions of the request
URL, so we do not feed ?-suffixed "arguments" to plain files, fail to
match filename extensions due to ?-suffixes, etc.

After this change, there are only two cases which use the "query"
portion of the request (the portion after the ?):

a) A redirect issued by HTTPD will redirect to the new file, but
with the same query string.

b) process_cgi() will, of course continue to use the query string.

rename bozo_err/bozo_warn/bozo_asprintf to bozoerr/etc.
new rule is that function that mirror libc-style functions get no underscore.

several clean ups:

- bozostrdup() gains a request parameter, and uses it to determine
what sort of error handling is required
- bozo_strdup() dies
- size_arrays() reduced slightly, pushing error handling into the caller
- convert to size_t for some array indices
- bozo_set_pref() and bozo_init_prefs() gain httpd parameters
- apply a bunch of manual CSE to vastly reduce the number of times the
string "request->hr_httpd" appears.
- CGI parse_header() takes a request not httpd now

XXX: lua glue updated to call bozo_init_prefs() with htttpd parameter,
but i'm only guessing here.

From Sergey Katsev at Coyote Point: fix bugs in request transformation and
CGI handling, including bin/40355 . There are two main changes here:

1) call process_cgi() after transform_request(), not before. Now it is
possible to have a default cgi handler catch a request for a path that
was produced by transformation, e.g. by index generation -- so now the
index can be "generated" by a CGI if that is what the user desires.

2) More clearly distinguish "file" from "query" portions of the request
URL, so we do not feed ?-suffixed "arguments" to plain files, fail to
match filename extensions due to ?-suffixes, etc.

After this change, there are only two cases which use the "query"
portion of the request (the portion after the ?):

a) A redirect issued by HTTPD will redirect to the new file, but
with the same query string.

b) process_cgi() will, of course continue to use the query string.

Initial revision

add ssl specific timeout value (30s). if SSL_accept() doesn't
work with in this timeout value, ssl setup now fails.

mostly different from, but inspired from the patch in PR 50655

o don't display special files in the directory index. they aren't
served, but links to them are generated.

- call this 20190116
- adjust the directory indexing again:
- don't include "index.html" in html headers
- additional escaping of names
- re-add top/bottom borders
- adds an aquamarine table header
- Zebra-stripes table rows using CSS instead of code
all from "Rajeev V. Pillai" <rajeev_v_pillai@yahoo.com>

use html tables for directory index.
from "Rajeev V. Pillai" <rajeev_v_pillai@yahoo.com>

call this bozohttpd 20181204.

many clean ups:
- keep a list of special files and their human names
- remove (void) casts on bozo_http_error()
- fix a few more misuses of bozo_http_error()
- rename check_mapping() to check_remap() and perform some CSE
- switch away from ``%s'' to '%s'
- remove a bunch of #ifdef using new have_feature defines

two fixes reported by mouse:
- don't check contents of 'st' if stat(2) failed.
- round up instead of truncate. now 10000 byte files say 10kB not 9kB.

from CHANGES:

o reduce default timeouts, and add expand timeouts to handle the
initial line, each header, and the total time spent
o add -T option to expose new timeout settings
o minor RFC fixes related to timeout handling responses

old timeouts:
60 seconds for initial request like, 60 seconds per header line,
and no whole timeout (though the recent total header size changes
do introduce one that would be about 11 hours.)
new timeouts:
30 seconds for initial request like, 10 seconds per header line,
and a total request time of 600 seconds.


the new global timeout is implemented using CLOCK_MONOTONIC, with
a fallback to CLOCK_REALTIME if monotonic time is unavailable.

this closes one additional memory leak found by JP. add a simple
test to check this.
