Implement the man(7) .MR macro, a 2023 GNU extension. The syntax and semantics is almost identical to mdoc(7) .Xr.
This will be needed for reading the groff manual pages once our port will be updated to 1.23, and the Linux Manual Pages Project is also determined to start using it sooner or later. I did not advocate for this new macro, but since we want to remain able to read all manual pages found in the wild, there is little choice but to support it. At least it is easy to do, they basically copied .Xr.

While the HTML standard allows multiple <h1> elements in the same document, <h1> is intended for top level headers, and most of the sections in a manual page can hardly be considered top-level. It is more usual to use <h1> only for the main title of the document of for the site name.
Consequently, move .Sh/.SH from <h1> to <h2> and .Ss/.SS from <h2> to <h3>, freeing <h1> for use by header.html in man.cgi(8).

Finally get rid of the archaic <table> markup for header and footer lines and use flexbox CSS instead. Improve accessibility by adding role and aria-label attributes to these header and footer lines. Using ideas from both Anna Vyalkova <cyber at sysrq dot in> and myself.
As a welcome side effect, this also resolves the long-standing issue that the rendering was always 65em wide, requiring horizontal scrolling when the window was narrower. Now, rendering nicely adapts to browser windows of arbitrary narrowness.

Split tagging into a validation part including prioritization in tag.{h,c} and {mdoc,man}_validate.c and into a formatting part including command line argument checking in term_tag.{h,c}, html.c, and {mdoc|man}_{term|html}.c.
Immediate functional benefits include: * Improved prioritization of automatic tags for .Em and .Sy. * Avoiding bogus automatic tags when .Em, .Fn, or .Sy are explicitly tagged. * Explicit tagging of .Er and .Fl now works in HTML output. * Automatic tagging of .IP and .TP now works in HTML output. But mainly, this patch provides clean earth to build further improvements on.
Technical changes: * Main program: Write a tag file for ASCII and UTF-8 output only. * All formatters: There is no more need to delay writing the tags. * mdoc(7)+man(7) formatters: No more need for elaborate syntax tree inspection. * HTML formatter: If available, use the "string" attribute as the tag. * HTML formatter: New function to write permalinks, to reduce code duplication.
Style cleanup in the vicinity while here: * mdoc(7) terminal formatter: To set up bold font for children, defer to termp_bold_pre() rather than calling term_fontpush() manually. * mdoc(7) terminal formatter: Garbage collect some duplicate functions. * mdoc(7) HTML formatter: Unify <code> handling, delete redundant functions. * Where possible, use switch statements rather than if cascades. * Get rid of some more Yoda notation.
The necessity for such changes was first discussed with kn@, but i didn't bother him with a request to review the resulting -673/+782 line patch.

Examples include roff(7) .ft, .ll, and .ta, mdoc(7) .Sm and .Tg, and man(7) .DT and .PD. Use this concept for a variety of improved decisions in various validators and formatters.

The .UR and .MT blocks in man(7) are represented by <a> elements which establish phrasing context, but they can contain paragraph breaks (which is relevant for terminal formatting, so we can't just change the structure of the syntax tree), which are respresented by <p> elements and cannot occur inside <a>.
Fix this by prematurely closing the <a> element in the HTML formatter. This menas that the clickable text in HTML output is shorter than what is represented as the link text in terminal output, but in HTML, it is frankly impossible to have the clickable area of a hyperlink extend across a paragraph break. The difference in presentation is not a major problem, and besides, paragraph breaks inside .UR are rather poor style in the first place.
The implementation is quite tricky. Naively closing out the <a> prematurely would result in accessing a stale pointer when later reaching the physical end of the .UR block. So this commit separates visual and structural closing of "struct tag" stack items. Visual closing means that the HTML element is closed but the "struct tag" remains on the stack, to avoid later access to a stale pointer and to avoid closing the same HTML element a second time later.
This also needs reference counting of pointers to "struct tag" stack items because often more than one child holds a pointer to the same parent item, and only the outermost child can safely do the physical closing.
In the whole corpus of nearly half a million manual pages on man.openbsd.org, this problem occurs in exactly one page: the groff(1) version 1.20.1 manual contained in DragonFly-3.8.2, which contains a formatting error triggering the bug.

Represent mdoc(7) .Pp (and .sp, and some SYNOPSIS and .Rs features) by the <p> HTML element and use the html_fillmode() mechanism for .Bd -unfilled, just like it was done for man(7) earlier, finally getting rid both of the horrible <div class="Pp"></div> hack and of the worst HTML syntax violations caused by nested displays.
Care is needed because in some situations, paragraphs have to remain open across several subsequent macros, whereas in other situations, they must get closed together with a block containing them.
Some implementation details include: * Always close paragraphs before emitting HTML flow content. * Let html_close_paragraph() also close <pre> for extra safety. * Drop the old, now unused function print_paragraph(). * Minor adjustments in the top-level man(7) node formatter for symmetry. * Bugfix: .Ss heads suspend no-fill mode, even though .Ss doesn't end it. * Bugfix: give up on .Op semantic markup for now, see the comment.

Finally, represent the man(7) .PP and .HP macros by the natural choice, which is <p> HTML element. On top of the previous fill-mode improvements, the key to making this possible is to automatically close the <p> when required: before headers, subsequent paragraphs, lists, indented blocks, synopsis blocks, tbl(7) blocks, and before blocks using no-fill mode.
In man(7) documents, represent the .sp request by a blank line in no-fill mode and in the same way as .PP in fill mode.

Now that the NODE_NOFILL flag in the syntax tree is accurate, use it in the man(7) HTML formatter rather than keeping fill mode state locally, resulting in massive simplification (minus 40 LOC).
Move the html_fillmode() state handler function to the html.c module such that both the man(7) and the roff(7) formatter (and in the future, also the mdoc(7) formatter) can use it. Give it a query mode, to be invoked with TOKEN_NONE.
