Drop the jemalloc_internal_includes.h umbrella

Convert the production source files in src/ (69 .c/.cpp) and
test/jemalloc_test.h.in to list the headers they actually use, then
delete the umbrella.  Three consolidated headers (peak_event.h,
prof_sys.h, sz.h) also gain explicit transitive includes.

Every translation unit now declares what it uses.  A missing include
now fails at the failing file rather than silently working because
something upstream pulled in the world.

- * jemalloc can conceptually be broken into components (arena, tcache, etc.),
- * but there are circular dependencies that cannot be broken without
- * substantial performance degradation.
- *
- * Historically, we dealt with this by each header into four sections (types,
- * structs, externs, and inlines), and included each header file multiple times
- * in this file, picking out the portion we want on each pass using the
- * following #defines:
- *   JEMALLOC_H_TYPES   : Preprocessor-defined constants and pseudo-opaque data
- *                        types.
- *   JEMALLOC_H_STRUCTS : Data structures.
- *   JEMALLOC_H_EXTERNS : Extern data declarations and function prototypes.
- *   JEMALLOC_H_INLINES : Inline functions.
- *
- * We're moving toward a world in which the dependencies are explicit; each file
- * will #include the headers it depends on (rather than relying on them being
- * implicitly available via this file including every header file in the
- * project).
- *
- * We're now in an intermediate state: we've broken up the header files to avoid
- * having to include each one multiple times, but have not yet moved the
- * dependency information into the header files (i.e. we still rely on the
- * ordering in this file to ensure all a header's dependencies are available in
- * its translation unit).  Each component is now broken up into multiple header
- * files, corresponding to the sections above (e.g. instead of "foo.h", we now
- * have "foo_types.h", "foo_structs.h", "foo_externs.h", "foo_inlines.h").
- *
- * Those files which have been converted to explicitly include their
- * inter-component dependencies are now in the initial HERMETIC HEADERS
- * section.  All headers may still rely on jemalloc_preamble.h (which, by fiat,
- * must be included first in every translation unit) for system headers and
- * global jemalloc definitions, however.
