Remove commented-out code across the engine

Sweep of ~650 lines of //-disabled statements, declarations, and calls
(plus three /*-wrapped dead blocks in htscoremain.c and htscore.c and
the MFC pApp remnant in htsserver.c). Prose comments stay, including
labels that describe live code; usage examples and config-knob docs
(HTS_TRACE_MALLOC, the htsweb.c DEBUG toggle) were kept. Insertions are
clang-format rewraps of live lines that became touched by the deletions.

 ## Build & test

-# ===========================================================================

-# SYNOPSIS
-#
-#   AX_ADD_FORTIFY_SOURCE
-#
-# DESCRIPTION
-#
-#   Check whether -D_FORTIFY_SOURCE=2 can be added to CPPFLAGS without macro
-#   redefinition warnings, other cpp warnings or linker. Some distributions
-#   (such as Ubuntu or Gentoo Linux) enable _FORTIFY_SOURCE globally in
-#   their compilers, leading to unnecessary warnings in the form of
-#
-#     <command-line>:0:0: error: "_FORTIFY_SOURCE" redefined [-Werror]
-#     <built-in>: note: this is the location of the previous definition
-#
-#   which is a problem if -Werror is enabled. This macro checks whether
-#   _FORTIFY_SOURCE is already defined, and if not, adds -D_FORTIFY_SOURCE=2
-#   to CPPFLAGS.
-#
-#   Newer mingw-w64 msys2 package comes with a bug in
-#   headers-git-7.0.0.5546.d200317d-1. It broke -D_FORTIFY_SOURCE support,
-#   and would need -lssp or -fstack-protector.  See
-#   https://github.com/msys2/MINGW-packages/issues/5803. Try to actually
-#   link it.
