Add ELF TLS to the release notes.

|
Minimize the TLS documentation examples (we don't need "dword" in a
mov from ebx, for example.) This is just to avoid user confusion.

Absolute relocation wrt ..tlsie for ELF32
Relative relocation wrt ..gottpoff for ELF64

Add new WRT type ..tlsie.
Generate R_386_TLS_IE relocation entries
for references to thread local variables.

Snapshot releases have *only* digits in the tail. "git describe"
produces tails that have digits in them, but aren't numeric.

Move all the version strings to a single compilation unit, ver.c; this
does not include the version macros, which are fed into macros.c.

Set default attributes for .tdata and .tbss sections
Implement new attribute 'tls' for arbitrary section names
Flag variables in sections with tls attribute with STT_TLS

Drop the data pointer, and instead assume the struct rbtree will be
embedded in a bigger data structure (to be extracted via
container_of()).

offsetof() is a C99 construct; provided here as an ersatz for older
systems.
container_of() is a nonstandard but highly useful construct, which
allows data structure control items like tree structures to be
embedded in larger data structures without the penalty of extra
pointers and allocations.

Implement library functions for "left-leaning red-black trees" with
uint64_t keys. This is meant for looking up symbols by address in the
backends that need to do so, e.g. ELF.
A good question is if there is a better way to do this, that recovers
the original symbol, but that's a future issue.

Remove duplicate entry for the "error" warning class; leave at the end
with "all", as being another meta-warning class.

Retroactively document the following changes to the warning options:
- gcc-like syntax (-Wfoo, -Wno-foo)
- "all" alias
- "error" metawarning
Added in 2.00rc1 but never documented.

These two really need to be done together, in order for constructs
such as %[%1] to work properly. Furthermore, fix a token-pasting bug
in expand_mmac_params().

Better grammar and fix incorrect description of the number-overflow
warning (it is not just limited to 64-bit arithmetic overflow, it also
triggers when trying to squeeze in a value which is too large into an
immediate.)

The code to parse the -w/-W options was updating warning_on[], not
warning_on_global[], but warning_on[] is reset at the beginning of
each pass (to let the warning directive work); as a result the -w/-W
options don't actually do anything at all.

Set STT_TLS in symbol table for symbols declared
in thread local storage sections. Note that,
for now at least, such symbols must also be
declared as GLOBAL.

Remove unnecessary duplicated patterns; with indirection we can handle
lists of any length.
For 16-bit generic padding, alternate between SI and DI dependencies.

Use expand_id() for the argument to %use, instead of expand_smacro().
This really makes more sense for a "naked" argument. This is a
semantic change, but is unlikely to break any real code.

When producing the mangled version number, don't add a subminor if
there isn't a patch level or release candidate number. Thus, 2.05p1
is 2.05.00.01, but 2.05 can just be 2.05.
