Triggers function object to execute on the first time step.

Example usage:

    minMax1
    {
        type            fieldMinMax;
        libs            (fieldFunctionObjects);
        writeControl    onStart;
        fields          (".*");
    }

Ref: EP2608

avoid heap allocations for pseudo-inverse of tensor/symmTensor (#3313)

See merge request !734

- Pstream changes (one-sided), local AMI communicators,
  other adjustments

- provide separate float/double UList interfaces, which improves
  flexibility (eg, with SPDP)

- sigFpe::fillNan_if() interface, for filling in when using alternative
  memory allocators

- previous code used derived string iterators, but these would
  be largely ignored anyhow since the underlying std::sub_match
  str() method would just yields a std::string anyhow.

  The SubStrings::str(size_t) method wasn't used in any code, so now
  just use std::string iterators only.

  This change simplfies overall handling, since it removes an unneeded
  template dependency.

- /usr/bin/{gcc,g++} normally just symlinks to clang/clang++
  and may have unknown default flags.
  For a gcc toolchain, it would be better to use a homebrew
  installation.

  For these cases, the compiler will need to be specified with
  version=.. in WM_COMPILE_CONTROL.

  For example, with "version=14", to select gcc-14, g++-14 from the
  homebrew installation.

- needs a slight hack for locating the FlexLexer.h header.
  Added into src/OSspecific/POSIX similar to how it is handled
  in src/OSspecific/MSwindows

CONFIG: add simple config/detection support for libumpire (Linux)

- new options to set components specified by homebrew.
  Sets version as system, path from brew --prefix

    -adios-brew, -adios2-brew, -boost-brew, -cgal-brew,
    -fftw-brew, -kahip-brew, -metis-brew, -scotch-brew,
    -gmp-brew, -mpfr-brew

    -with-homebrew
     Shortcut for selecting all the above (except gmp, mpfr)

* additional special treatment for GMP and MPFR.

  If using non-system locations and not part of the ThirdParty
  compiler, they can additionally be set in the CGAL config file:

    -gmp-brew, -gmp-path
    -mpfr-brew, -mpfr-path

- easier to create type-specific looping in templated code

STYLE: pass 'direction' and 'label' by value instead of reference

COMP: qualify Foam::min() in dense matrix classes

DEFEATURE: remove POSIX regex interface (#3343)

See merge request !733

- compiler versions are now sufficient that only the C++ regex
  interface is now being used. Can remove the old POSIX code
  accordingly.

  This change also removes any dependency on the SubStrings class to
  manage the matching results.

ENH: remove OpenFOAM dependencies from MacOS addr2line utility

additional topology-aware handling for Pstream

See merge request !731

- minor adjustments to some BCs construction:
  * ensure origin/axis are zero-initialized
  * use dictionary get<> instead of lookup

- convenience, avoids creating intermediate fields and for
  gWeightedAverage() requires one fewer reduction

ENH: combine loops for FieldField averaging

STYLE: remove clip() function, superseded by clamp_range() - JAN-2023

- generate .cc (instead of .C) intermediate files, consistent with how
  we manage other generated code and makes them less case sensitive

BUG: fan: bc value not updated. See #3211

See merge request !701

STYLE: mark Pstream::scatterList() as deprecated

- this entry point is not directly used anywhere, only the
  scatterList_algorithm backend is actually used.

  The scatterList() routine is misnomer since it actually works like a
  broadcast that skips overwriting the local rank, but only if used in
  combination with the gatherList() manual implementation that uses
  the same walk pattern.

- can be used to simplify some logic. For example,

      if
      (
          (tok.read(is) && tok.isWord("FoamFile"))
       && (tok.read(is) && tok.isPunctuation(token::BEGIN_BLOCK))
      )
      ...
  vs
      if
      (
          (is.good() && (is >> tok) && tok.isWord("FoamFile")) ...
       && (is.good() && (is >> tok) && tok.isPunctuation(token::BEGIN_BLOCK))
      ) ...

- the number boundary faces before the first processor patch.
  This approximately equals the 'real' number of boundary faces

- also fixes a compilation issue introduced by f13be4f6
  (where the direct assignment from SLList to List was removed)

- compiler cannot decide between std::string and std::string_view
  when creating from 'const char*' without also supplying the size,
  so also supply a 'const char*' constructor.

ENH: additional string_view handling for ITstream and SubStrings

- the 'move' treatment performs a shallow copy but does not alter
  the passed parameter. Identical semantics as per std::span.

ENH: constexpr for basic HashTable constructors

STYLE: 'Foam::zero' instead of 'const Foam::zero' for containers

- this is simply a compiler dispatch flag, so the additional 'const'
  qualifier is unnecessary

- should ideally avoid SLList in most cases, since it is allocation
  intensive and most places can easily use DynamicList or
  CircularBuffer instead.

STYLE: use push_uniq instead of deprecated appendUniq method

- mark with a 'normal' deprecation instead of 'strict' deprecation

- the '-no-core' to limit coredumps to zero size
- the '-quick' option, which changes valgrind --leak-check from "full"
  to "summary", and implies -no-core as well.
- enforce tcp libfabrics provider under valgrind since valgrind
  does not otherwie work nicely with RMA

- fails with MPI_ARG_ERR.
  Do not assume that any vendors actually support in-place handling
  for MPI_Reduce(), regardless of what their documentation may claim.

increased use of intrinsic data types and ops for communication
