[hzy199411]

1. add strings.h to fix strcasecmp issue

/home/hzy/build/PXView/libsigrok/strutil.c: In function ‘sr_parse_sizestring’:
/home/hzy/build/PXView/libsigrok/strutil.c:343:19: error: implicit declaration of function ‘strcasecmp’; did you mean ‘g_strcasecmp’? [-Wimplicit-function-declaration]
  343 |         if (*s && strcasecmp(s, "Hz"))
      |                   ^~~~~~~~~~
      |                   g_strcasecmp

2. add strings.h to fix strcasecmp issue

/home/hzy/build/PXView/libsigrok/input/in_wav.c: In function ‘get_wav_header’:
/home/hzy/build/PXView/libsigrok/input/in_wav.c:47:23: error: implicit declaration of function ‘strcasecmp’; did you mean ‘g_strcasecmp’? [-Wimplicit-function-declaration]
   47 |         if (l <= 4 || strcasecmp(filename + l - 4, ".wav"))
      |                       ^~~~~~~~~~
      |                       g_strcasecmp

3. add sr_dslogic_option_value_to_code2 declaration to fix implicit function declaration issue

/home/hzy/build/PXView/libsigrok/lib_main.c: In function ‘ds_dsl_option_value_to_code’:
/home/hzy/build/PXView/libsigrok/lib_main.c:1022:24: error: implicit declaration of function ‘sr_dslogic_option_value_to_code2’; did you mean ‘sr_dslogic_option_value_to_code’? [-Wimplicit-function-declaration]
 1022 |                 return sr_dslogic_option_value_to_code2(lib_ctx.actived_device_instance, config_id, value);
      |                        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      |                        sr_dslogic_option_value_to_code
