Abseil LTS branch, Aug 2023, Patch 1 (#1534) · fb3621f4

* Add StdcppWaiter to the end of the list of waiter implementations

Since ABSL_INTERNAL_HAVE_STDCPP_WAITER is defined on all systems
it is effectively a fallback. I left the condition there in case
we have to disable it on some platform in the future.

PR #1498: Fix order of link options in pkg-config files · 407f2fdd

Imported from GitHub PR https://github.com/abseil/abseil-cpp/pull/1498

In Windows, a few libraries (`dbghelp`, `advapi32`, and `bcrypt`) are added via link options. However, the .pc files produced for pkg-config erroneously include them before the abseil libraries. This can cause undefined references when trying to build against abseil.

This commit swaps the order and adds the custom link options after the abseil dependencies. The following is a list of `.pc` files affected by this and the additional link options used:

* all: `-L${libdir}`
*  `absl_base.pc`: `-ladvapi32`
* `absl_random_internal_seed_material.pc`: `-lbcrypt`
* `absl_symbolize.pc`: `-ldbghelp`

Closes https://github.com/abseil/abseil-cpp/issues/1497

GetInlinedDataUninitialized() is removed. Just use GetInlinedData() in

uninitialized memory.  In these cases it is immediately constructed.

InlinedVector: Fix control-flow-inregrity warning when using a class · 511ad649

with a vtable

The code is getting the pointer, then constructing it on the next
line. Using reinterpret_cast on this pointer is legal according to
https://clang.llvm.org/docs/ControlFlowIntegrity.html#bad-cast-checking,
but it flags it anyway. The docs say it might be necessary for
`allocate()`-type APIs, and recommends adding them to an ignorelist.

Also note that std::addressof is removed. It is unnecessary since
inlined_data is a char-array.

Add a special case for erase(begin(), end()) to reset the control bytes. The motivation is to avoid potentially expanding the table unnecessarily later.

Note: I prefer doing this as a special case in erase(iterator, iterator) rather than special casing erase(iterator) for size==1 because IIUC that changes the time complexity of erase(iterator) from O(1) to O(N) and in pathological cases, it could change loops from O(N) to O(N^2).

Cleanup `//absl/strings/internal/memutil.h` · b2a6c1bc

`memmatch()` is only used in `string_view.cc`, so move it there.
The moving of `memmatch()` to `string_view.cc` decouples `string_view`
from `memutil`, which will allow us to move `string_view` into its
own target in a followup.

The only other function that is used is `memcasecmp()`, so delete
all other functions.
