ipc: Makefile.am: Pick already compiled UHDDevice.o object

Take the chance to reorder LDADD, since it expects dependencies to be in
inversed-tree order.

Depend on libosmogsm explicitly

Transceiver52M/device/common/bandmanager.h uses gsm_freq102arfcn() from
libosmogsm, so we should include libosmogsm.

configure.ac: Avoid building shared libraries by default

Those libraries are internal to osmo-trx and won't be installed,
so there's no use in building them.

transceiver: add optional Laurent burst LUT modulation (int16)

Introduce an optional Burst LUT optimization for Laurent-based burst
modulation, enabled via --with-burst-lut.

- Add precomputed Laurent LUT tables (float and int16 I/Q variants)
- Generate LUT at initialization (prepareBurstLUT)
- Use LUT-based modulation for sps=4 when enabled
- Keep original modulateBurstLaurent() as fallback
- Add configure.ac option and USE_BURST_LUT define

This reduces runtime computation by replacing per-burst Laurent
processing with memcpy-based LUT lookups.

build: install common/GSM/transceiver libraries for emscripten and add pkg-config files

Expose previously internal libs (libcommon, libGSM, libtransceiver_common)
when building with emscripten, install headers and generate .pc files.
Keep them noinst for native builds.

debian/*.install: make paths consistent

Some of the paths start with a leading slash and some don't. Both
variants work, but this is confusing. Let's go without the leading
slash, because the paths are releative (in this case to debian/tmp where
"make install" puts the files during debian packaging).

checkpatch.conf: lint more code

The current linter configuration misses to find lots of formatting
errors as we've seen here:
https://gerrit.osmocom.org/c/osmo-trx/+/42198/comments/f8f1b5a2_3c7e1389

This is caused by the following exclude rules in .checkpatch.conf, which
were added there to avoid that some of the checkpatch rules don't work
correctly with C++ code:

  ---exclude .*h
  ---exclude Transceiver52M/grgsm_vitac/.*
  ---exclude utils/va-test/.*

Fix this by splitting the .checkpatch.conf into two files,
.checkpatch.c.conf and .checkpatch.c++.conf. Let the C version use the
default rules. Let the C++ version ignore the rules that don't work with
C++ code:

* SPACING
  Fails on:
    std::vector<std::string>
  With:
    ERROR:SPACING: spaces required around that '<' (ctx:VxV)
    ERROR:SPACING: spaces required around that '>' (ctx:VxW)

* FUNCTION_ARGUMENTS
  Fails on:
    ScopedLock lock(mLock);
  With:
    WARNING:FUNCTION_ARGUMENTS: function definition argument 'mLock' should also have an identifier name

* INDENTED_LABEL
  Fails on:
    private:
    protected:
  With:
    WARNING:INDENTED_LABEL: labels should not be indented

* NEW_TYPEDEFS
  Fails on:
    typedef std::map<K,D*> Map;
  With:
    WARNING:NEW_TYPEDEFS: do not add new typedefs

With the new config, the linter only complains about the following
things across the existing C++ code, which seem to be legitimate linting
problems (and if not, can be ignored as well):

  BRACES_NOT_NECESSARY, CODE_INDENT, LEADING_SPACE,
  MULTISTATEMENT_MACRO_USE_DO_WHILE, OPEN_BRACE, POINTER_LOCATION,
  PRINTF_I_OSMO, SINGLE_STATEMENT_DO_WHILE_MACRO, SPACE_BEFORE_TAB,
  STATIC_CONST_CHAR_ARRAY, TABSTOP, TRAILING_WHITESPACE

checkpatch.conf: lint more code

The current linter configuration leads to too many linting errors, as
seen here:
https://gerrit.osmocom.org/c/osmo-trx/+/42198/comments/f8f1b5a2_3c7e1389

Fix this by not excluding files where the linter generates false
positives. But instead ignoring specific rules that generate these false
positives (mostly related to this being a C++ code base). The following
rules are now ignored:

* SPACING
  Fails on:
    std::vector<std::string>
  With:
    ERROR:SPACING: spaces required around that '<' (ctx:VxV)
    ERROR:SPACING: spaces required around that '>' (ctx:VxW)

* FUNCTION_ARGUMENTS
  Fails on:
    ScopedLock lock(mLock);
  With:
    WARNING:FUNCTION_ARGUMENTS: function definition argument 'mLock' should also have an identifier name

    protected:
